 A board for mixing VGA signals with sound and all kind of other signals. A build in Arduino generates a VGA signal, too. Each colour has its own chanel, Red Green, Blue.\\ A board for mixing VGA signals with sound and all kind of other signals. A build in Arduino generates a VGA signal, too.

 +HSYNC and VSYNC signals are squared pulses of +5V, and the RGB signals take values in a continuous analog voltage range from +0V (absolutely dark) to +0.7V (maximum brightness).\\
