Desk light
There is a light on my desk. I invite you to change its color.
One of the first things you do with an Arduino or ESP32 is make an LED blink. It’s the canonical Hello World of microcontrollers. I’m taking that a step further: you pick a color for my LED and I’ll send you back photographic proof.
Think of it as a way of saying Hi while you’re on my site.
Known issues
The OV3660 camera module has a fixed focus and my current cardboard enclosure (!) places the display too close to the lens. I’m working on a 3D printed enclosure that results in clear pictures and isn’t susceptible to breaking if I look at it the wrong way.
