As shown in the circuit diagram we need only 3 Arduino terminal pins, pin 8 is for the push button which toggles the motor direction of rotation. Pins 9 and 10 are PWM signal outputs, at any time ...

Overview of the L293D Motor Driver The L293D is an H-bridge motor driver integrated circuit used to control DC motors and stepper motors. It allows the direction and speed of motors to be controlled ...

Use Arduino IDE 1.8.19 for programming. The potentiometer sends an analog signal to the Arduino Nano, which adjusts the PWM signal to control motor speed. The seven-segment display outputs motor speed ...

Figure 1. Arduino Uno. available to control a DC motor [8]. The Arduino Uno is one of the most common starter boards that are being used to control multiple kinds of motors, especially DC motors, ...

The circuit in the figure provides three levels of speed control for a dc motor, using a PC’s parallel port (LPT1). A C++ program performs the control functions by allowing the signals from the ...
