Blink an LED

Turn a light on and off with o1, pwm() and wait().

🔌 Wiring

Connect an LED to output o1.

To switch o1 on, give it power with pwm(100) — that means 100% power. To switch it off, set it to 0.

wait(500) makes the board wait for 500 milliseconds — that is half a second.

TinkerPy
setup:

loop:
    o1 = pwm(100)
    wait(500)
    o1 = 0
    wait(500)
On for half a second, off for half a second, forever.
💡 Tip

Press Run on the simulator first — you will see the LED blink on screen before you even plug in the board.

🚀 Your turn

Make it blink faster (try wait(100)) and then slower (try wait(2000)).
