The internship was on ‘Embedded Systems and Wireless Communication’. We started off with soldering and Printed Circuit Board design. I was introduced to a number of microcontrollers and microprocessors along with their applications in the real world. I then studied architecture and programming of AVR and 8051 microcontrollers and MSP, ARM and DSP microprocessors to explore the potential of these microcontrollers and microprocessors. The programs that we did included the programming of peripherals like LEDs, LCD, ADC, DAC, Serial, UART, I2C, SPI, PWM, Timers, Stepper motors, DC motors, Infrared Sensors, Servo Motors, HALL Sensors, Temp sensor LM35, Bluetooth Module which were interfaced with the above mentioned microcontrollers and microprocessors. I also explored the various simulation softwares which included Proteus and TINA.
