16F84 Programmable Chip on R/C Car

The project refers to a remote controlled car that utilizes a 16F84 programmable chip and C code.

The brain of the project is the 16F84 programmable chip. It is very limited and an obsolete chip. The MPLAB ICD2 is used as the programmer since it is powerful and can program several PICs. The implemented software utilizes Piklab an IDE to code which can provide all the required operations from programming and compiling, to pin diagrams of the chips. CCS is used to compile the code. Any type of input can be taken by the 7085 chip and then convert it to a 5V power supply. It can also be used to build a USB power charger.

The 4-pin MC14066 chip switching transistor was used for opening and closing circuits. Only the 2.5V signal that comes out from the PIC can be used for power if there are no transistors. Those motors with the LPT port can be turned ON and OFF using an IR540 MOSFET transistor that will require 5V at its gate and the PIC only gives out 2.5V.

There are several programmable chips that can be used such as AVRs.
