I have been doing Arduino, PIC and ESP8266 microcontrollers programming for my clients since 2015 at different freelancing platforms. Some of my related projects are: 1). Line following robot 2). USB Webcam 3). Audio Amplifier 4). Home automation 5). Power bank programming 6). Intelligent energy control room as reference to occupancy I have worked on many of the sensors i.e. Ultrasonic Sensor, Temperature Sensor, IR Sensor, LDR, Humidity Sensor, Motion Sensor, Pressure Sensor, Sound Sensor etc. I have also used on LCD, Motors, Buzzer, Relay, IoT, Data Communication while doing ESP8266 and Arduino programming. I'm open to unlimited revisions because client satisfaction is my first priority, as I believe a satisfied client comes back for another work. So, you don't need to worry about your design. Looking forward to work with you. Thank you. Waseem
