can light up your room, study space, or Maker area giving it a awesome cool look. Moreover it is very easy to build and helps you get creative with electronics and coding. The circuit diagram for a 4 ...

You can fade out and fade in the light of an LED automatically by using Arduino and a simple code that is described below. Even though the Arduino board cannot output variable voltage on its digital ...

Looking for a simple circuit to control the light intensity of Light ... With the help of the Power Mosfet, we can use the low voltage output from the Arduino ports to control high voltage/current ...

The pullup resistor is nothing but a high-value resistor connecting to the Arduino digital pin you are using with the HIGH (5v) voltage. In the setup function, the pin mode for the LED and pushbutton ...

it looks like multiple LED’s are lit up simultaneously. [Alex] planned to use an Arduino to control this display, but it doesn’t have enough outputs on its own to control all of those lights.

In this circuit, we are making a Light Sensor using LDR with Arduino to control a bulb/CFL as per light condition ... Here, we are defining the Pins for Relay, LED and LDR. #define relay 10 int LED = ...

Solder the battery pack to the Arduino. An Arduino is ... Draw a grid on your sweater. You can use any knit sweater, but light-colored ones work best, as the LED light will bounce around more.

This Arduino sketch simulates traffic lights using three LEDs: red, yellow, and green. The traffic light operates in a sequence of red for stop, yellow for ready, and green for go. Once the sketch is ...
