Propose a marketable microcontroller-based system using at least 3 different input / output devices provided by PicsimLab software. The proposed system must have the following properties:

i. The code is developed in MPLAB software.

ii. It represents a meaningful system

For example: A washing machine. The push button RB3 represents start/stop button, the push button RB4 represents wash/rinse/spin button, and servo motor represent the motor of washing machine.

iii. It is developed using PIC16F877A

iv. It can be simulated using PicsimLab software
