N H bridge module can be used with motors that have a voltage of between 5 and 3. V DC. With the module used in this tutorial, there is also an onboard 5. V regulator, so if your supply voltage is up to 1. V you can also source 5. V from the board. So lets get startedFirst, lets see the little steppers in action Our main character, StepperBot, is instructed to move in a square path on my coffee table, making 90 degree turns. Choosing the right DC Motor or DC gear motor for a specific application can be a daunting task and many manufacturers only provide basic motor specifications. These. Electronics Tutorial about DC Motors, Electrical Motors and Stepper Motors used as Actuators including PWM and Transistor Hbridge Motor Control. First well run through the connections, then explain how to control DC motors then a stepper motor. At this point, review the connections on the L2. N H bridge module. Consider the following image match the numbers against the list below the image DC motor 1 or stepper motor ADC motor 1 or stepper motor A 1. V jumper remove this if using a supply voltage greater than 1. V DC. This enables power to the onboard 5. V regulator. Connect your motor supply voltage here, maximum of 3. V DC. Remove 1. 2V jumper if 1. V DCGND5. V output if 1. V jumper in place, ideal for powering your Arduino etcDC motor 1 enable jumper. Leave this in place when using a stepper motor. Connect to PWM output for DC motor speed control. IN1. IN2. IN3. IN4. DC motor 2 enable jumper. Leave this in place when using a stepper motor. Connect to PWM output for DC motor speed control. DC motor 2 or stepper motor BDC motor 2 or stepper motor B Controlling DC Motors. To control one or two DC motors is quite easy with the L2. N H bridge module. First connect each motor to the A and B connections on the L2. N module. If youre using two motors for a robot etc ensure that the polarity of the motors is the same on both inputs. Otherwise you may need to swap them over when you set both motors to forward and one goes backwards Next, connect your power supply the positive to pin 4 on the module and negativeGND to pin 5. If you supply is up to 1. V you can leave in the 1. V jumper point 3 in the image above and 5. V will be available from pin 6 on the module. This can be fed to your Arduinos 5. V pin to power it from the motors power supply. Dont forget to connect Arduino GND to pin 5 on the module as well to complete the circuit. Now you will need six digital output pins on your Arduino, two of which need to be PWM pulse width modulation pins. PWM pins are denoted by the tilde next to the pin number, for example Finally, connect the Arduino digital output pins to the driver module. In our example we have two DC motors, so digital pins D9, D8, D7 and D6 will be connected to pins IN1, IN2, IN3 and IN4 respectively. Then connect D1. 0 to module pin 7 remove the jumper first and D5 to module pin 1. The motor direction is controlled by sending a HIGH or LOW signal to the drive for each motor or channel. For example for motor one, a HIGH to IN1 and a LOW to IN2 will cause it to turn in one direction, and  a LOW and HIGH will cause it to turn in the other direction. However the motors will not turn until a HIGH is set to the enable pin 7 for motor one, 1. And they can be turned off with a LOW to the same pins. However if you need to control the speed of the motors, the PWM signal from the digital pin connected to the enable pin can take care of it. This is what weve done with the DC motor demonstration sketch. Two DC motors and an Arduino Uno are connected as described above, along with an external power supply. Then enter and upload the following sketch. Bart Davenport Physical World Rare. Arduino digital pins. Modeen. A, OUTPUT. Modeen. B, OUTPUT. Modein. 1, OUTPUT. Modein. 2, OUTPUT. Modein. 3, OUTPUT.

One we turn the motors on and run them at a PWM value of 2. This is not a speed value, instead power is applied for 2. Then after a moment the motors operate in the reverse direction see how we changed the HIGHs and LOWs in thedigital. Write functions. To get an idea of the range of speed possible of your hardware, we run through the entire PWM range in the function demo. Two which turns the motors on and them runs through PWM values zero to 2. Finally this is demonstrated in the following video using our well worn tank chassis with two DC motors Controlling a Stepper Motor. Stepper motors may appear to be complex, but nothing could be further than the truth. In this example we control a typical NEMA 1. It has 2. 00 steps per revolution, and can operate at at 6. RPM. If you dont already have the step and speed value for your motor, find out now and you will need it for the sketch. The key to successful stepper motor control is identifying the wires that is which one is which. You will need to determine the A, A, B and B wires. With our example motor these are red, green, yellow and blue. Now lets get the wiring done. Connect the A, A, B and B wires from the stepper motor to the module connections 1, 2, 1. Place the jumpers included with the L2. Student Hobbyist Electronics Projects Tutorialsby Lewis Loflin. View all of my You Tube Videos. Also visit and subscribe to My You. Tube Channel. Tweet. Introduction The purpose of these pages is to introduce the student and hobbyist to electronics projects. My hope is generate interest for those thinking about entering a high tech field, or simply to have fun. Ive been a part time adjunct professor at a local community college teaching electricity and electronics. My electronics website reflects what Ive taught or been asked to look into by visitors. I have 4. 0 years experience in electronics from vacuum tubes to modern solid state and industrial controls. In college I had a year each of physics, chemistry, and biology along with C, C. Pascal, and assembly. How to use this Website. This site has been up for about 1. Arduino, some PICAXE Microchip PIC and semiconductor components such as transistors, zener diodes, etc. I assume the user has at least some knowledge of Ohms Law and can use a volt ohm meter. All of the example circuits have been built and tested I do not use simulation software such as SPICE. I dont use or have circuit boards for the projects, one will have to design their own. When I do build a projects I use point to point wiring by hand. I have limited financial resources and part of the lesson is use what resources one has. Nothing here is intended to be used as commercial product or used in one. Most of the projects use low voltages, but the few that dont such as AC power controls are presented as information only you assume all risk. New Arduino Stepper Motor Coil Winder. You.

I taught myself the coding for Arduino, PICAXE, Raspberry Pi, Microchip PIC, Debian and Slackware Linux, CSS etc. I approach in a way to give my students a basis for their own projects. Every page on this website was hand coded by me every project built and tested. My education philosophy is learn the basics, find working examples, then use what works as a foundation for further learning. Modify and try new ideas. Id say my job title would be applied technologist. First and foremost read this safety warning. Unless one wants to use batteries, the only practical solution is a plug in the wall power supply. General Electronics Learning and Projects. At 3 inches long this basic Arduino does ten times what the KIM 1 will do. Cost is under 5. Arduino Micro controller Projects. My Arduino section is growing. For example we can interface the thermocouple amplifier and an LCD display to the micro controller to display the temperature in say the flue of a wood stove. Again the idea is modular, small projects that can be built into bigger projects. For more technical details on the Arduino see ATMEGA1. Arduino Micro Controller Projects. Arduino Microcontroller Projects presents a number of tested projects and examples for Arduino. The emphasis is hardware control which suggest one has an electronics background. Its also helpful to have a background in digital logic and binary code. The projects will explain this as needed. What differs here is I avoid the use of Arduino only code and code libraries in order to port the basic code to Python or Microchip PIC C. Raspberry Pi and Linux. Raspberry Pi and Linux is an ARM processor based mini Linux computer clone. It has addressable hardware IO to connecting external circuitry. These projects are in Python a high level interpreted language finding many modern applications. Here I again concentrate on hardware interfacing and an introduction to setting up the operating system in Debian Wheezy and installing a real time hardware clock. The Linux I setup here can be used in any Debian based system even a common PC. Python is SLOW compared to C used on Arduino, but is great for a user interface. So I look into alternative interface setups to use say An Arduino to handle low level electronics. I also use light Debian programs for Raspberry Pi ported over from Damn Small Linux and Puppy Linux because as a PC Pi is slow and weak. Many of the operating systems often touted elsewhere some will hardly operate. Instead of LXDE I use JWM and Openbox. Here I concentrated on building a fast Linux based operating system to get some weaknesses in Raspberry Pi. Connecting PC Printer Port to External Electronics. Below are listed a series of projects using pyparallel and electronics. We will use a common PC printer port to learn basic python and electronics interfacing. Starting with routines I wrote to aid students Id advise walking through this in sequence. Have fun and send comments andor corrections to lewisbvu. Connecting a PC Printer Port to Electronics with Python is closely related to Raspberry Pi. It too is a nearly identical Linux system but differs in being designed to use a hardware printer port as I O to connect electronics projects. The projects here too are in Python and with modifications will work on Raspberry Pi and vise versa. It differs in I never bothered to setup the I2. C interface found in Raspberry Pi instead interfaced an Arduino to better handle low level electronics. Now a available for download a custom live Linux distribution to use a PC printer port for electronics control without installing or altering the PC in any way.

F6. 28. A and PIC1. F6. 83. While cheap and versatile controllers theres a steep learning curve in using assembly. Introduction to PIC1. F6. 83 Programming. PICAXE Microcontroller Projects. Finally we come to the PICAXE Microcontroller in this case a medium range PICAXE 1. M2. While built hardware wise on a Mircochip PIC controller it has an easy to learn built in proprietary basic. Its designed for students rather more than serious applications. The PICAXE series of micro controllers rank as the easiest and most cost effective way to use Microchip processors. I wanted an easier and less expensive way to introduce my students to the PIC micro controller. Here I hope to get those starting out past poorly written literature and lack of simple working code examples.
