After some hunting around we found a neat motor control module based on the L2. N H bridge IC that can allows you to control the speed and direction of two DC motors, or control one bipolar stepper motor with ease. The L2. 98. 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 started 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. A NEWFullfeatured GPSNMEA Parser for Arduino. TinyGPS is a new Arduino library for parsing NMEA data streams provided by GPS modules. Like its predecessor. 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.

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. Slackware Old Versions on this page. 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.

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.
