I have good knowledge in c and c++ development for Micro controller , i wrote code for many driver like DIO, I2C, LCD, UART, SPI by c language for AVR microcontroller. 2- saving lighting power by motion detection i used pic microcontroller and pir sensor and light sensor to save the power consumption int the street 3-RC car used TM4C123GH6PM "arm cortex" and bluetooth module and smart phone to remote control the motion of the car by smart phone. 4- warehouse robot used AVR microcontroller atmega128, RFID, ultrasonic, line follower, zigbee module, and five DC motors with their power driver. 5- wireless area body sensor network used group of sensor collecting data from patient and send it through zigbee to the control unit
