Starting our Easter holiday coding sessions simple, using a Raspberry Pi Pico to flash an LED using MicroPython via Thonny on a RPi4
Started with a bit of a stumbling block as wrongly assumed the breadboard ports on the Pimoroni Pico explorer ran horizontal but they actually run vertically!
Once components had been switched (and also the LED anode the right way round) we had a simple flashing LED.
This was the code we used…
from machine import Pin
import utime
led = Pin(4, Pin.OUT)
led.low()
while True:
led.toggle()
print("Flash")
utime.sleep(1)Thrilling isn’t it 😄
Circuit as follows:
GND to 330 ohm resistor
330 ohn resistor to LED cathode
LED anode to Pico GP4
