Code Explanation: We declare the pins the we are going to use for the photoresistor and led diode in lines 1 and 2. At line 3, 4, 5, 6 we need to declare the function of the components that we have ...

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 ...

Three red LEDs (LED1 through LED3) provide visual indication, driven by transistor T1. T1’s base is connected to pin D4 of the Arduino Nano via resistor R1. Audio indication is provided by a 230V AC ...

This project demonstrates how to represent a decimal number (from 0 to 15) as a 4-bit binary output using an Arduino. It uses four LEDs connected to GPIO pins to display the binary equivalent of the ...

This water sculpture can stop drops of water in mid-air. This is accomplished by flashing LEDs to illuminate the droplets at just the right time. But it’s not limited to blinky lights alone. … ...
