This is to be followed after you have successfully completed the following steps: Installed mikroC Pro for PIC on your PC. Installed the programmer software that came with your PIC programmer. If you have got an iCP01 USB PIC programmer from iCircuit Technologies, you should install Microchip’s PICkit programming software. Got a breadboard and a regulated +5V power source. Basic setup on the breadboard As mentioned before all the experimental circuits will be constructed on the breadboard because it is easy to modify the circuit and correct any wiring error. Figure 1 shows the pin diagrams of PIC16F688. It is

Regulated Power Supply for Your Breadboard

Posted on by 9 comments

Embedded systems require electric power to operate. Most of the components in them including the processors can operate at a wide range of voltages. For example, the operating voltage range for PIC16F688 is from 2 to 5.5 V. It means you can supply power from three AA size batteries (4.5 V) and it will work just fine as long as the battery voltage doesn’t fall below 2 V. But there are certain applications where you need a regulated constant voltage for safer operation of the embedded system. For instance, any application that uses analog-to-digital converters (ADCs). ADCs require a fixed
