I want the motor to do exactly the same movement i.e.
#Two dc motors arduino code code
I’d like to introduce a switch so that when the motor shaft turns 360 degrees exactly, the switch is activated and the code starts again from the beginning. Thanks for posting this, I’ve got it all working well. Post navigation ← Creating Robots using Arduino – H-bridge Compiling Arduino sketches using Makefile → This entry was posted in Tutorials and tagged Arduino, DC Motors, pwm, Robots on Jby Sudar. It’s going to be existing, so don’t miss it 😉 Next week we will see how we can put together all we have learned so far and build a complete bot. Note: I am still working on adding support for changing the speed(pwm) as well. Check out the examples sketches inside the /examples folder of the library. Instead of setting the pins individually, you can call the following directions to change the direction of the motors.

The library is available in github from where you can download it. I have encapsulated the logic of changing directions of DC motors in an Arduino library called DCMotorBot. Here is the modified sketch that you can use to change the direction as well as the speed of the DC motors.

#define I4 13 // Control pin 2 for motor 2ĪnalogWrite(E1, 153) // Run in half speedĪnalogWrite(E2, 255) // Run in full speedĪnalogWrite(E1, 255) // Run in full speedĪnalogWrite(E2, 153) // Run in half speed #define I3 12 // Control pin 1 for motor 2 #define I2 9 // Control pin 2 for motor 1 #define I1 8 // Control pin 1 for motor 1 The value you pass to analogWrite function will decide the speed of the motor. You just have to replace the function digitalWrite with analogWrite in last weeks code. This is because pins 10 and 11 are PWM pins. Remember, I asked you to connect the enable pins of H-bridge to pins 10 and 11 of Arduino. You can just reuse the same circuit from last week. If you pass a value between 1 and 254, then the speed of the motor will vary accordingly. If you pass 0, then the motor will stop and if you pass 255 then it will run at full speed. Remember the value can be between 0 and 255. The speed of the motor depends on value that was passed to the analogWrite function. To control the speed of the motor, all we need to do is to replace digitalWrite function on L293D enable pins to analogWrite. In Arduino Uno, it works on pins 3, 5, 6, 9, 10 and 11. This function takes a value between 0 and 255 and doesn’t work on all pins in Arduino. If not, then checkout the PWM tutorial from Arduino reference.

If you have tried out the LED fade example in Arduino, then you already know how to use it. In Arduino, the analogWrite function allows you to generate a PWM wave in a pin. Analog Writeīefore we go ahead, we need to know about analogWrite function in Arduino. Also I will talk about how we can encapsulate the entire logic into an Arduino Library. This week we will see how we can control the speed of the motor as well using the IC. Last week, I explained how we can control the direction of DC motors using the H-Bridge L293D IC. In this article we will see how we can control the speed of the DC motor using Arduino.
