Arduino Leonardo is a micro-controller board based on the ATmega32u4. This board form factor and functionality is quite similar to Arduino UNO (7.1 cm x 5.3 cm x 1.5 cm ; 20 g) , with the exception that the USB interface is built into the micro-controller itself instead of using external serial-USB converter IC on →
Sparkfun has pretty interesting to look at article How LEDs are Made. How LEDs are Made factory tour article shows how LED supplier YunSun (Shenzhen China) makes LEDs.

When testing with Arduino circuits, it is often useful to see digital signal states on different pins. It is easy to measure single signal pin state with multimeter, but when you want to monitor several pins visually you need something else. One useful option is to use LEDs connected to pins to show their state. →
Rubic’s Cube had it’s 40th Anniversary this week.
