simple relay with lcd display here is code: from machine import Pin import time from pico_i2c_lcd import I2cLcd i2c = machine.I2C(0, sda=machine.Pin(8), scl=machine.Pin(9), freq=400000) I2C_ADDR = 0x27 lcd = I2cLcd(i2c, 0x27, 2, 16) I2C_ADDR = 0x27 lcd = I2cLcd(i2c, 0x27, 2, 16) a = Pin(0,Pin.OUT) while True: a.value(1) lcd.putstr(‘on’) time.sleep(1) lcd.clear() a.value(0) lcd.putstr(‘off’) time.sleep(1) lcd.clear()
