The work comprises software for the PIC and hardware for the software. The PIC controller uses an EasyPIC-6 board and includes a PC-interfaced programmer for the PIC chip. It has many external modules: 128 × 64 graphic LCD dis- play, 2 × 16 LCD display, 4 × 4 keypad, and port expander, all in the same bench. The trainer is capable of 36 experiments in logic/analogue electronic and control systems. A 5-sided approximate sensor, two photoelectric sensors (BR56-DDT-P and BEN9M-TFR),four CMOS,four BCD-7-segment driven by CD4511B, two relays (2-pole and 3-pole), six voltages, ammeter measurement, DC motor, and 24VDC power supply, connect through connectors and pinions. Results of all the experiments show the trainer satisfying requirements of undergraduate and postgraduate pro- jects involving conventional electronic and classical control systems.

The first microprocessors had external peripherals such as memory, input-output lines, and timers (Matic, 2021 ). In time came a new device called integrated circuit (IC), which contains both processor and peripherals. Also called a microcontroller, this was the first chip with a microcomputer [1,2]. Peripheral
