Here is a simple Arduino Camping Light project. In this design, only one push button switch is used to control the light output (from a bunch of white LEDs) between off, dim, medium, and full ...

number 2 is 00000010 so only the second led from the right will be on. Now lets see the schematic and how I’ve connected the 8 leds + resistors and 1 button + pull-up resistor to the Arduino Board ...

When the Arduino code sees the button getting pressed, it brings the corresponding LED pin high and starts a fade out timer using the SoftPWM library by [Brett Hagman]. It’s worth noting that ...

The $87.36 Arduino Plug and Make Kit comes with an Arduino UNO R4 WiFi microcomputer featuring Bluetooth and its own built-in 12 x 8 LED matrix ... and a set of three buttons.
