How It Works The LDR is connected to a voltage divider circuit to produce an analog signal proportional to the light intensity. The analog signal is read by the Arduino via pin A0. The program ...

I had the idea of building this Arduino icicle lights project during the making of the light dimmer circuit and the result can be seen below. Is not a complicated project so it can be done easily by ...

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 ...

digitalWrite (TXLED, LOW); // set the LED on delay (1000); // wait for a second } TXLED and RXLED hardware connection The Arduino Micro is closely related to the Leonardo, with some small difference.

It is a pretty common first project to use an Arduino (or similar) to blink an LED. Which, of course, brings taunts of: you could have used a 555! You can, of course, also use any sort of oscillato… ...
