STEPPER - A stepper motor connected via a standard stepper motor driver (Step/CLK & Direction) Current supported motor types are as follows:ĭCMOTOR - A standard DC type motor driven via a transistor or driver module.ĭCMOTOR_H_BRIDGE - A standard DC motor connected via a H-Bridge driver module allowing for forward and reverse directions. You can simply add motors by using the libraries 'Attach' function and remove them using the 'Detach' command. It also allows you to mix motor types and connect them to any available digital pins (you are not limited to just PWM pins). The library makes use of the Arduinos hardware interrupt timer 2 to drive the motors in the background leaving your sketch totally free for you main program. This Arduino library (current only supports ATMega328p based Arduinos) will allow you to control one or more DC or stepper motors from you Arduino. L298N is not easy to use with 3.3v Gpio of raspberry pi, so I implemented the same logic with a relay board. The most common way to implement H-bridge is IC L298N. It is the only way to drive motor forward ,stop and reverse. The microcontroller PIC16F877A reads RA0 analog value and stores the digital value on variable (i), this variable is used to set duty cycle of the active PWM (PWM1 or PWM2).An Arduino library for controlling DC and stepper motors Relay H-bridge (Relay Motor controller) For contro a dc motor you needan h-bridge. PIC16F877A Timer2 is configured to generate a PWM signal with a frequency of 500Hz and the microcontroller runs with 8MHz crystal oscillator. The PIC16F877A microcontroller needs to be supplied with 5V between oins VDD and VSS.ĭC motor control with PIC16F877A CCS PIC C code: The basic elements of the H-bridge are the four MOSFETs (2 N-type and 2 P-type). The easiest way to do that is with an H-Bridge IC, like the L293D ( datasheet ), or the SN754410NE ( datasheet ). If direction 1 button is pressed the microcontroller starts PWM1 (RC2 pin) and stops PWM2 (RC1 pin) and if direction 2 button is pressed the microcontroller stops PWM1 (RC2 pin) and starts PWM2 (RC1 pin), when the stop button is pressed the microcontroller stops PWM1 and PWM2 signals and the motor will stop. You need to be able to reverse the current in the two coils A1A2 and B1B2, much like reversing the current across a DC motor to get it to spin forward and backwards. The microcontroller PIC16F877A reads analog data from channel 0 and use the digital value to set the PWM duty cycle. The motor speed is controlled from potentiometer connected to RA0 (analog channel 0). The two LEDs indicate rotation direction, if Direction 1 button is pressed the motor moves in the first direction and LED 1 on and the same thing for Direction 2 button and LED 2. There are 3 push buttons in the circuit 2 of them to choose rotation direction and the other one stops the motor.

PORTB internal weak pull-ups are enabled in the software and therefore there is no need to add a pull-up resistor to pins RB0, RB1 and RB2.
