Our purpose here is to explore the potential of PIC12F683 microcontroller for which we need a development board. The good thing is we are going to make our own board. The schematic and the actual board that I have built are shown below. I soldered all the components on a 12 x 8 cm general purpose prototyping board.
Completed Board
It has following features in it:
1. A Regulated +5V power supply.
2. 3 Output LEDs that can be connected to any GPIO pins using jumper wires.
3. ON/OFF power supply switch.
4. A Green LED as a power ON indicator.
5. An 8-pin IC socket for PIC12F683 microcontroller.
6. Two potentiometers: one for providing Vref, and other for simulating analog input to ADC.
7. An ICSP header connector.
8. Two tactile switches for input operation.
9. A TTL to RS232 level shifter using a transistor circuit.
10. A piezo buzzer.
11. A DC motor with driving circuit.
