This isn’t about connecting a temperature sensor in your Arduino. This build is about using the temperature sensor in your clock. The ATMega328p, the chip at the heart of all your Arduino Uno ...

He suspected EMF interference so as a quick first step he decided to throw together an EMF detector using an Arduino. It uses a bank of LEDs as an indicator bar to reflect the EMF picked up by the ...

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 ...

If the analog output (AO) of the module is connected to an analog input (for example A0) on the Arduino you can expect to read a value of 0 (0V) when in its upright position and 1023 (5V) when it is ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I ...

What if you could get an instant SMS alert the moment a fire or smoke is detected at home or office? Through this project ...

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 ...

pH sensor), use a programming app available on major desktop operating systems, and are relatively affordable and easy to source (there are plenty of Arduino clones you can get for cheap ...
