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.

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.

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 ...
