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 ... receiver IR1 is only ...

Now that you've seen how to blink your Arduino's LED, we'll use one final, slightly more complex example: we'll use a third-party UNO breakout board and an external traffic light sensor board to ...

This makes for a stronger difference signal, so when the Arduino reads the sensors, it’s much clearer which way PHIL should point the sensor head to follow the light. The builder, [Sean O ...

Most ambient lights and sensors are designed to generate light to even out the picture on the front of the panel and reduce any light bleed from the back of an LCD display. This Arduino-powered ...

Because of the affordability and seeming ubiquity of the Arduino platform, they have been hard at work this last month trying to get their Geiger counter sensor board for an Arduino out the door.

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures ... you can use a smaller package microcontroller, for example a 8 ...
