VGA Signal Generator
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.
For the Arduino one could use the code of that project: https://www.gammon.com.au/forum/?id=11608.
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).
