Hi,
I would like to recommend the following to anyone interested in making something nice with a PIC. The image shows the schematic and the actual probe built on my breadboard.
**broken link removed**
It is a probe with 16 functions which includes:
- Logic Probe
- logic pulser
- Frequency Counter
- Event Counter
- Voltmeter
- Diode Junction Voltage tester
- Capacitance Measurement
- Signal Generator
- NTSC Video Test Patern
- Serial Port tester giving out Ascii characters
- Midi Note
- R/C Servo tester
- Sqaure Wave generator
- Pseudo Random Number generator
- ir38 infrared red LED driver
- PWM waveform output (6KHz, 3% to 97% duty cycle)
As you can see, the schematics is very simple and no additional transistors or ICs required. I use a 16F876 and programmed the hex code by the author into it and it work as expected.
The author has also provided the source code to the project so one can learn the technique in implementing the different functions using PIC.
There are also other PIC projects in the above website so you can look around. Most of them have schematic, object code and source code for download.
