WebbSimple control of the LED. Let’s write a minimal program to simply power on and power off the LED. ... To do that you just have to use one simple command: GPIO.output(), with either GPIO.HIGH to power on the LED, or GPIO.LOW to power off the LED. GPIO.cleanup() And we finish the program by cleaning up the GPIOs, with GPIO.cleanup(). WebbCommand (GPIO/Value) Extra information. GPIO,, GPIO: 0 … 16. State: 2 (HIGH-Z, input) 1 (HIGH, output) 0 (LOW, output) Basic on/off.. We can control a pin with simple http URL commands. To change the pin to high or low steady output. Setting GPIO to 2 means that it will be able to detect low level relays (with high impedance, Z ...
