Descrição
A case for a large red button I made to play mp3 sound effects when the button is pressed.
I printed the case to store the electronics. Holes for main button, secondary button, power switch, micro usb and mini selector switch.
The main button is a 100 mm massive arcade button. The secondary button is a 24 mm arcade button.
I used Wemos D1 mini (ESP8266). MAX98357A DAC is used for mp3 playback, with a 3W 4ohm 50mm speaker. Powered by Li-ion battery with TP4056 charger module and MT3608 boost module.
