Hi Everyone !
I have an IR LED, phototransistor, max 232 and RS232. Actually, i try to make the connections of these. First of all, I know that I should use an ADC before max232.(I am right ?). I need to use ADC for phototransistor. But, I consider that for IR LED, should I use DAC after RS232's output ?
As a result, can anybody help to establish the exact circuit ? :/
Predicted circuit schematic is attached. Let' s make it work![:)]( "Smile :)")
