By using a DPDT Relay and as a given connection in the diagram you can move a DC motor in forward and reverse direction. This is the Simulation video of dc motor direction controller using relay and pushbutton.
Welcome to this video on Arduino Tutorial for Beginners. This video about Analog Signal Output (PWM)
This video shows how to control speed of DC Motor with a little bit transistor knowledge. Arduino lacks a true analog output, so we need to use Pulse-width modulation (PWM) to simulate a variable DC supply voltage. PWM is a common procedure for supplying variable power levels to “slow” electrical devices such as resistive loads, LEDs, and DC motors. Pulse-width modulation (PWM) provides the ability to simulate varying levels of outputs.
Arduino Uno has 6 PWM pins: Digital I/O pins 3, 5, 6, 9,10, and 11
I have discussed basic theory for Direction control of robot by controlling movement of DC motor. How to perform basic movement operations like forward, backward, left, right etc. As L293 motor driver IC have been used here, so i have discussed operation of L293 and how to connect it with microcontroller and dc motor, I have used ATmega328P microcontroller, Program is written in Embedded C, used Microchip Studio editor, and ultimately run the hex code in Simul IDE to see the animation of output.
