Playdate Flashlight

Well I’m unsure if you were serious about this question, so here’s an explanation: The Playdate SDK does not have support for controlling the LED on the lock button, but there’s a little exception when you think hard enough. When the device is taking microphone input, the LED lights up with a bright orange. Since barely anybody uses the microphone, not a lot of people realized, but since I was working on an app that heavily involved the microphone for like 3 months, I noticed very quickly. From there you just run pd.sound.micinput.startListening() for turning on the LED, and pd.sound.micinput.stopListening() to turn it off.

I hope you weren’t joking. Also, here’s basically the entire logic of it:

if pd.buttonJustPressed(pd.kButtonA) then
        on = not on
        if on then
            playdate.sound.micinput.startListening()
            gfx.clear(white)
            gfx.setColor(black)
            gfx.setDitherPattern(0.5, gfx.image.kDitherTypeBayer8x8)
            gfx.fillTriangle(199, 109, 151, -1, 247, -1)
            flashlight_on:draw(183, 93)
        else
            playdate.sound.micinput.stopListening()
            gfx.clear(black)
            flashlight_off:draw(183, 93)
        end
    end
