Way too late for the Valentine’s Day yet maybe just in time for the Mother’s Day this year, I’d like to introduce an electronics project that came about as a result of my reluctance to throw away a nice looking empty box. This year Valentine’s Day came around just about the time I was playing with ATTiny13 micros – I was setting my Arduino IDE up to be able to write code for and burn the program into smaller 8-bit AVR MCUs like ATTiny13. Once the box of chocolates has been freed of its original content by my dear wife Tanya, on the way to the trash I turned it over and realised that there’s a lot of space available inside the plastic insert. I could easily tuck a battery, an MCU and a bunch of LEDs in there for a nice blinking light effect.
