Smile Detection With Raspberry Pi Using Opencv and Python
Great idea. Plan on making this soon. Quick question though. Can we use a cheaper version of raspberry pi. Like I dont see why the 3 model B is needed?
I used 100k for both r1 and i also used 47nF capacitor in parallel from the middle to ground and 10uf capacitor (polarised) in series from the center v out
Ok. I love this. Im making a few ajustments to allow the lights to hold a solid color and let them cycle. Im having trouble seeing how you soldered the micro controller. If you could explain a bit better. I think i got it from the schematic and the picture but im unsure. If you could carify this that would be great
