The sensor is really just an infrared photodiode inside of a tube. The diode is connected to an analog input pin on an Arduino. The sensor can be pointed at an object, and the Arduino can sense ...

At the heart of the bot is the MPU6050 – a combo accelerometer/gyroscope sensor that keeps track of tilt and movement. An Arduino Uno takes this data, runs it through a PID loop, and commands an ...

A pressure sensor which can detect height differences of as little as 50cm uses MEMS technology developed by Omron. The sensor module can measure altitude, atmospheric pressure or water depth in ...
