Hack a humidifier with an AtTiny

 

This is a refreshingly simple hack on which I spent only a few hours, most of which were actually for installing Atmel Studio to program the AtTiny 🙂

Lightweight software UART -> custom serial

Software UART to custom serial on an AtTiny45, and then going to the Peggy2 board

7 months ago, in the middle of the winter, it all started with this…

IR Remote (Syma s026) dedicated board – V2 – AtTiny45

IRcmdS026_AtTiny45_Final_Side1

Right, the previous post was about creating a dedicated board that can do 2 things:

1. read and decrypt the IR commands sent by the Syma s026 remote control
2. send them via a serial link (to the “central” MCU or elsewhere)
