This lesson describes how to control both the speed and direction of a DC motor using Python and a L293D chip. After we have declared our variables and set a required speed in RPM, everything else in the main code is the same as the previous position control post where we calculate our quadrature encoder counts (void Achange() and Bchange() ) and set our PID terms to produce an overall PWM value (void findMotorData())to drive a motor to reach a steady state. Three-Phase Brushless Direct Current (BLDC) motor, by using feedback from three hall sensors. The central pin of the potentiometer is connected back to pin 9. Arduino - Ifâ ¦else if â ¦else statement - The if statement can be followed by an optional else ifelse statement, which is very useful to test various conditions using single ifelse if statement. Introduction. DC motor sends the calculated value (called feedback value) back to Arduino. Kangaroo x2 adds self-tuning feedback motion control to your Sabertooth or SyRen motor driver. An Implementation of PID controllers for the speed control of a DC motor is given in this report.
