I have done many electronics projects based on Arduino and Raspberry Pi programming. I have designed more than 250 PCBs design for different projects and commercial usage. I have more than 4 years of experience and make more than 400 projects. I have designed many projects related to Automation, Motor Control, Sensor Calibration, and custom board to achieve different projects with varying applications. Some of the Arduino type of calibration of the sensor but here is the list of some common Arduino compatible sensors I have worked on Commonly Used Sensors: Metal sensor, Smoke sensor, Humidity and Temperature Sensor, Heartbeat sensor, Gas sensor, Gyro, RFID, The sound detector, Motion sensor, IR sensor, Flow sensor, Accelerometer, Gyroscope and many more Actuators: Relays, Motors (DC, Stepper, Gear, Servo and Induction motor), Speaker, SD card module, Buzzers, LCD, and many more.
