Add nRF2401 & Arduino Functionality to Hacked #IKEA Molgan LED Lamp | @IKEAUSA
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
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.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
