PIC Project #3: "Bargraph.tpr"
PicTools Manual 3.0
Once everything is operating to your satisfaction, you can program your PIC with the HEX
file :
Once you have programmed the PIC, you're ready to try it in your circuit. Make sure the
power to your circuit is off, and then plug in the PIC. When you turn the power on, the
display should show "0". If you push the button, the value on the display should
increment.
If your project appears "dead", double-check the circuit (power, RC oscillator,
connections, etc).
This project is relatively simple, but it uses the more complex PIC16C74. The ’74 has
many good features, which have made it a popular device. This project demonstrates
how to read a single analog input and then display the result on an 8-segment LED
bargraph.
The schematic below shows the circuit. The PIC itself requires just three parts to operate:
a 4-MHz crystal and two capacitors to form its oscillator. The remaining three parts are a
10K potentiometer, a 330-ohm resistor, and an 8-segment LED bargraph (common
anode).
