This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

So we can use a simple formula for routine calculations: “level = 255/5 x effective voltage” The experimental code for ATtiny85 is the same as the Arduino Sketch, as indicated. The only deviation is ...

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

The ready to use, fully assembled circuit board has everything ... with a specially written Arduino library and a dozen pre-made examples. Maker LED display also has Wi-Fi so it can connect ...

To actually power and control the entire circuit, [Martyn] used an Arduino loaded up with a program ... and warning indicators working with the LED bar array / tachometer, everything will look ...

When you read “Arduino wristwatch”, you fall into the ... [Marijo Blažević’s] creation is much more polished than that. A round circuit board holds two surface mount ICs and 12 LEDs.
