Arduino l293d motor speed - Arduino Playground - AdafruitMotorShield
The L293D is a dedicated module to fit in Arduino UNO R3 Board, and Arduino MEGA, It is actually a motor driver shield that has full featured Arduino Shield can
Overview Arduino is a great starting point for electronics, and with a motor shield it can also be a nice tidy platform for robotics and mechatronics.
Im using a potentiometer to control the speed of two generic 68V DC motors. The potentiometer input is scaled from to 0255, I then use the analogWrite.
Video embeddedThis instructable will guide you through the parts and steps to control a Dc motor's speed and direction with the help.
Drive motor using L293D SN, one can change the speed of motor by potentiometer. (1K) then connect 2 pins of L293D to 2 digital output pin on Arduino.
