Week 6 L293D Motor Driver IC
How the motor driver Works Download specification q Using a Breadboard Using the Pico pico_code\hbridge.py #This is the pin out starting from the top left (Notch is the top) #Pin 1 enable = GPIO pin 1 (PWM pin) #Pin 2 = GPIO pin 2 #Pin 3 OUT 1 = motor lead 1 #Pin 4 GND = GND Pi #Pin 5 If using an external power source connect to the ground of that. #Pin 12, 13 are also GND that can be used to ground the external power supply or Pico #Pin 4,5,12 and 13 are internally connected so can be used for any ground. #Pin 6 = motor lead 2 #Pin 7 = = GPIO 3 #Pin 8 (Vs) = 3.3V on Pico (Supplies power to the motor) Can use external power. #Pin 16 (Vss) = 3.3 V Powers the board logic #IC pins are numbered 1 and up anticlockwise. # pin 16 is top right.
