Let's get physical and assemble a circuit and control it with our Pi Zero

Requirements

1. Breadboard
2. Resistor(s)
3. LED(s)
4. Male to female wires
5. Raspberry Pi Zero, screen, keyboard, mouse and adaptors to make it all work

Summary of Steps

1. Make the circuit - resistor from + to one of the rows above; long LED ends to resistor rail; short LED ends to negative rail (-)
2. Connect to Pi Zero - from GPIO 21 to positive on breadboard (+); from GND to negative on breadboard
3. Check Pi GPIO Schematic to be sure of numbers
4. Open Python 3 IDE
5. Open a new file and save it with a name... e.g. led.py
6. Here is a simple script

from gpiozero import LED
from time import sleep

leds_on = LED(21)

while True:
  leds_on.on()
  sleep(1)
  leds_on.off()
  sleep(1)

8. Save the file
9. Run the file using Run module.
