A load cell interfaced to an HX711 Load Cell Amplifier allows an Arduino Nano to measure the mass of the CPAP machine plus the integrated water reservoir.

The Saturn’s electronics aren’t sophisticated enough to implement a lean burn system simply, and so [Robot Cantina] did what any of us might have done: hacked it in with an Arduino.

Built your very own parking sensors for the car using nothing more than an Arduino board and cheap components you can find online ...

Arduino, by contrast, is not a full computer but a microcontroller. Devices like the Arduino Uno or Nano excel at reading analog sensors, controlling motors, and maintaining precise timing.
