The build relies on an Arduino Uno as the brains. It’s equipped with an L293D motor driver shield to run ... [Maker 101] gave the Arduino an infrared sensor which can pick up signals from ...

Arduino is a great way for today’s novices to start ... Analog pin A4 is for the temperature sensor, digital pin D2 is for the infrared receiver module, and digital pins D4, D7, and D8 handle the LED ...

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

This specific sensor was chosen because others have successfully interfaced it with the Arduino. Not having to reinvent the wheel is good thing! For the build, [Brian] decided to hook up the IR ...
