PIC superprobe project gained its popularity because of simplicity of design. It uses very few widely accessible electronic components.
This small tool can serve as:
- Logic probe – for detecting High or Low voltage level;
- Logic pulser – for generating pulses with various rates;
- Event counter – for frequency counting;
- Voltmetter – for measuring voltages up to 5V;
- Diode junction voltage probe – for displaying diode voltage drop ;
- Capacitance meter – for measuring capacitors from 0.01uF to 100uF;
- Signal generator – for generating 500Hz square wave signal;
- Video patter generator – for generating NTSC video frames;
- ASCII generator – for generating Letter from A to Z leaded by cr/lf code;
- Midi note generator;
- R/C servo pulses;
- Square wave generator – from 1 to 9999Hz;
- Random number generator;
- IR LED signal generator – allows to send 38kHz signals during IR led testing;
- PWM generator;
And all that functionality is controlled by two buttons while information is displayed on four 7 segment LED displays. I’d say this is a “must have” tool. Source code of project is here. Also check out the Hall Of Fame of all reproductions of this nice tool.
