Or how to turn this:
Thanks to Yveaux for sharing this project over at OpenHardware – Yveaux shows how to turn a cheap, $5 lamp into a project with wireless/radio functionality and Arduino Pro Mini compatibility.
Powered from 3 AAA batteries Motion PIR sensor, which switches on the LED light for some time when detecting motion. Nice, compact enclosure Mounting plate Cheap, approx. E 4,99
Atmel ATmega328P microntroller, compatible with Arduino Pro-Mini nRF24L01+ 2.4GHz radio module (not WiFi!) Optional ATSHA204 CryptoAthentication chip Default sketch implements a MySensors enabled motion sensor Serial connector for programming sketches ISP for programming the ATmega directly LED light function can be removed, either partially or complete, to save battery power Quite cheap, around E 10,- including Molgan.
The project consists of a custom PCB, which is mounted on top of the original Molgan PCB. I had the custom PCB produced in white, to prevent it from being visible trhough the semi-transparent cover of the Molgan.
