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 ... of IRED1. The infrared ...

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 ...

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 ...

[Jordan’s] sensor includes just a single pixel. The sensor is really just an infrared photodiode ... he added an ambient light sensor. The Arduino can detect the amount of overall ambient ...

Most ambient lights and sensors are designed to generate light to even out the picture ... it's a little advanced for a first Arduino-based project, so tread carefully if you want to try this ...

It’s a fairly simple project, too: just hook an Arduino Uno up to a motion sensor ... but I’ve found clear plastic can interfere with infrared light. You can just leave the power relay on ...
