Tiny Doorbell Remote
These are the project files (hardware schematic and Arduino firmware code) for a small remote-control module that acts as an auxiliary remote to a wireless doorbell.
The hardware is built around the Attiny85 IC and a cheap 434 RF link transmitter.
A Fritzing schematic is in the hardware folder.
The circuit runs on a single 3V battery and consumes
- 65 μA while on standby mode
- 7.5mA while transmitting
Estimated battery lifetime: at least 60 days.
There are some general guidelines and files in the api directory for creating a HTTP POST endpoint on a Raspberry Pi, to control the module via the web.
