1. Module 5 - 8051 Microcontroller - Basics -  14 ~ 16 hours

Pre-requisite for this module:

• Understanding of Basic Electronics, Usage of electronic components in circuits, usage of bread boards and multimeter
• Basic understanding of what a microcontroller us and how it is different than a microprocessor
• Interface of various inputs/output devices including 16x2 LCD display, 4x4 keypad, usage of L293 board and electromechanical devices
• It is strongly recommended that students bring their own laptop. You’ll preserve your work and you’ll have all the development environment set up for you to work even after your course(s)

 Working Kit Contents:

• 8051 Development Board, USBASP SPI Flashing Board, DC Motor, Servo Motor, L293 Motor Driver Board, 16x2 Character LCD display, Breadboard, LEDs, RGB LEDs, Resistors, Potentiometer, 8x8 Dot Matrix Display, 7-Segment Display, Tactile switch, Rocker switch, Piezo Electric Buzzer, Connecting Wires, Batteries

 What you’ll learn:

• Interfacing and controlling basic components from the microcontroller
• Know how to use Keil 8051 compiler in your projects and how to flash the code using XploreFlash and USBAsp SPI programmer
• Interfacing electromechanical devices like DC/Servo motors, changing direction using H-Bridge like L293 boards
• Usage of timer/external interrupts and how to use them in understanding how we can get away with software delays and software polling
