Hello all
I've built this motion detection circuit and it work fine,
**broken link removed**
but I want to add a status led hooked directly after the two diodes and I dunno how to calculate current there for a transistor and the correct resistor to get it saturated?..
all I know is that voltage is 3.2 or 0 volts...
Is there a way to physically measure these things or it has to be computed/simulated?
thanks[/img]
