Here is a simple Arduino Camping Light project. In this design, only one push button switch is used to control the light ... This part number (and ofcourse the LED type) is not very critical. If you ...

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 ...

PIC, AVR, and Arduino are ubiquitous in projects ... We’ve embedded video of the circuit controlling an LED after the break. This IC ends up in a lot of projects so dig through your parts ...

The input circuit is a simple keypad matrix. To read each button push, the Arduino ... To ground the LED busses, we’ll be using four 2N2222 transistors. The Arduino will trigger each transistor ...
