What should you pick when you want to build a touchless lamp or light switch? A sensor of course! This is a design of a touchless lamp with a common and cheap reflective optical sensor. With a ...

Sure, countless microcontroller development boards featuring a USB connection have made it to the Projects and Tutorials pages of Electroschematics. Although these days it really is easy to build your ...

It might not seem too impressive these days, but when microcontrollers with hardware USB support were more expensive and rare, the VUSB library was often used to create USB devices with an ATtiny85.

Adafruit’s Trinket and digiStump’s Digispark board are rather close cousins. Both use an ATtiny85 microcontroller, both have USB functionality, and both play nice with the Arduino IDE. [Ray] is a fan ...
