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 ...

The robot uses a whopping 32 IR sensors to follow a black line across a concrete workshop floor, adjusting its path using a steering motor salvaged from a power wheelchair. An Arduino Mega Pro ...

We’ve featured loads of IR Arduino projects and they are all exciting ... Maybe he will add a temperature sensor someday so it doesn’t have to run on strictly time. A more complicated problem ...

But there was more work to be done after that, which is where the Arduino and a "9 Degrees of Freedom" sensor stick entered the picture. The quadcopter project team explains its work here ...

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 ...
