ES8266 powered, recyclable grow clock for children.
Made out of reused cardboard since these devices are only useful while children learn when to wake. I used an Arduino originally but switched to an ESP8266 because the clock was still being used and wanted to use NTP time via wifi.
I use platform.io cli but the Arduino IDE will work just as well.
Connect a servo to ground / Vcc and the signal wire to pin D4.
