Shield contains two L293D motor drivers and 74HC595 shift register. Supports motor voltages from 4.5 to 25 volts. Can control up to four DC motors or two stepper motors
Circuit uses PIC16F877A microcontroller and L293D motor driver IC. Three pushbuttons control motor direction and stop. Two LEDs indicate motor rotation direction. Motor operates at 12V nominal voltage
Robots are electromechanical devices capable of autonomous decision-making. Motors convert electrical energy into physical motion. Most robots use direct current (DC) power from batteries
Electric motors convert electrical energy into mechanical energy through shaft rotation. AC motors use alternating current to create rotating magnetic fields. DC motors use direct current to energize armature and create electromagnetic field
Uses TL494 and IRF1405 IC for 12V-30V power supply. Maximum current up to 20A with soft start capability. Adjustable pulse frequency from 100Hz to 1.1KHz. Features 10uS rise/fall time and 1.5uS/1.6uS gate rise/fall
DC motor controllers control speed and direction using PWM signals. Motor stops when joystick is at center position. Joystick movement controls motor direction and speed. Motor speed increases as joystick moves away from center
