How does it work? Each LED is grouped with an infrared (IR) LED and a photo-transistor. When a photo-transistors “sees” a certain wavelength of light, it is gated and turns on, allowing current to...
Schematic for LM78XX regulator series.
Just connect a 0.33uF capacitor (ceramic) from the input of the regulator to ground, and do the same with the 0.1uF capacitor. That would give an output of xV (...
