The LED should turn on when either the first button or the second button is pressed. Only use your Arduino for power and ground. Create a video (or a screencast) of your circuit in action. If you have ...

This LED DIMMER is an Arduino Uno based PWM (Pulse Width Modulation ... first consider a simple circuit as shown in figure below. Now if the switch in the figure is closed continuously over a period ...

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

The most important thing, however, is that with a very little effort, your panel can be highly customized to your needs by changing the function of each button/switch/LED or adding new ones. I'm quite ...

The complete code for this Arduino reed switch project is given at the end of this article. The code is split into small meaningful chunks and explained below. In this part of the code we have to ...

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino ... In case of any doubt refer this table. Push Switch (S1) ...
