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 ...

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 ...

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 ...

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 ...

I have used an Arduino Uno to monitor two ultrasonic sensors in the base of the Dalek and send the results over the USB serial interface to a Raspberry Pi which then plays an MP3 clip. I used a ...

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

If you’re working on an air quality monitoring project and space is at a premium, SparkFun’s latest Qwiic breakout board ...

The Arduino Nano Connector Carrier is a compact add-on board designed for the Arduino Nano boards to allow easy connection to ...

The array of switches, sensors, actuators, motors, and displays offers terrific versatility. The kit includes an excellent project guidebook. The Arduino software (called Integrated Development En ...
