The sensor shown here is essentially two plates mounted side-by-side, attached to an Arduino Nano using the Capacitor library which uses just two pins, one digital and one analog.

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.

Connect the VCC (Red) and GND (Black) wires of the water flow Sensor to the 5v and Gnd of Arduino, and link Pulse Output (Yellow) wire of the water flow sensor to Arduino’s digital pin 2. Note that ...

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...

Each sensor can be communicated with using I2C from analog pins 4 and 5 on the Arduino Uno. We powered the sensor stick using the 5 volts out available on the Arduino Uno.

Sensor-less brushless dc motors do not have to be hard to drive, ... p-channel mosfet pairs to switch motor current, plus a dc supply of 4.2 to 50V. The motor is controller using trapezoidal drive ...
