This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot ...

It needed power — so first I soldered red wire to the 5v spot on the sensor and plugged it into the 5v pin on the Arduino. Then I soldered a black wire to plug into the Arduino’s ground pin.

This DIY gas leakage detector is designed for educational and basic monitoring purposes. For critical safety applications, ...

For instance, if you want a light to flash every time a motion sensor detects movement, just plug an LED into one of the output pins and a motion sensor into one of the input pins.

Nice method and analysis. The temp sensor 3 pin devices are simple and cheap but good for 0.5 deg C precision or nearly a full degree in human measure.

Next steps shows how the master (Arduino) reads from the slave I2C device. Wire.requestFrom(address, 1) command expects to receive 1 byte of data from the TC74 sensor. Wire.available() waits for data ...
