Life Band monitors the health conditions of elderly up to date and provide immediate medical assistance if necessary.

As a free flying paragliding pilot, I have finally built my own simple but effective instrument that plays beep-beep during climb and so on.

In this project, I will show you how we can use a 3€ IR distance sensor to build a proper DIY tachometer that functions properly.

This project is about an Arduino Library to control the BK1086 and BK1088 devices. It was based on "BK1086/88E BROADCAST AM/FM/SW/LW RADIO R
