- During analog to digital conversion with PIC the noise occurs
- The problem is current from the supply because it does not absorb enough the noise ,We have developed a circuit for it (together with my brother) ;-)
- Circuit transformer, capacitor and diode is comprised of. Operating logic, capacitors absorb noise.
- Three output transformer should be selected. Because the output (+9v) (GND) (-9v)
- IMPORTANT! – Works with PIC s 5v circuit voltage of 5 volts should regulate, or PIC will be damage!!!.(9v>5v regulator circuit)
Required Materials
