Arduino demo board
I often use Arduino to play and dev some apps, but I often experienced many issue with prototyping board and wire, lot of short circuit and bad contact. So I have made this small board, just need to plug Arduino, four buttons are available, a rotatif encoder, all I/O are available on terminal block, a 2×16 LCD is also available on I2C, or with conventional connection.
