Low-voltage LED Lamps are easy to control from a microcontroller when. If you want to turn on more leds then set other pins as OUTPUT and HIGH. To make this simple project we need these following components : 3 Led ( red, yellow, blue ) 3 Resistance ( 220 Ohm ) Electrical wires Arduino UNO. A collection of lighting projects controlled by microcontrollers. PinMode(13, OUTPUT) // set pin 13 as outputĭigitalWrite(13, HIGH) // set pin 13 as high or 1 This is a very simple arduino project where a led is turned on by setting the pin 13 as output, then write it with a high value, in our case that means that pin 13 will deliver 5 volts. You can use an external one or use the one soldered on the board (pin 13). 2 days ago &0183 &32 Using the WiFi option, users can connect to the Arduino Cloud or other platforms to easily create connected projects. Let’s start with the simplest led project which consists in turn on an LED. Every step will have the code, the schematic, photos of the project and sometimes a video tutorial. I have recorded a short video of the Arduino RGB LED Spinning Night Light in action.In this article I will add some simple Arduino LED projects starting with basic ones like how to turn on an LED, blinking, and more. There are also cooler looking digital ones like the Hakko)
