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. Every step will have the code, the schematic, photos of the project ...

Download the codes here Arduino simple shield potentiometer code: Arduino shield rc car: Arduino nano module L298P code: ...

I had this idea of building my own bicycle lighting system totally personalized, the lights would have the exact lighting ...

(D6 of Arduino connected to Din of WS2812B) It is highly recommended to connect a 100nF capacitor across the ‚5v and Gnd‛ connection, and a 100-470 Ohm resistor in series with the ‚Din‛ line of the ...

For Arduino beginners like us, this is where you paste the code from other people's projects. When you send the code to the Arduino from your computer, the code is stored on the Arduino itself.

Next it was time to install the electronics. [Stef] used an off-the-shelf RGB LED matrix from Adafruit. The matrix is configured with 16 rows of 32 LEDs each. This was controlled with an Arduino Uno.

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].

A Light Emitting Diode (LED) should light up once the Arduino has power and after a second or so, an LED on the board should start slowly blinking. The image below points out these LEDs on the board.

Sometimes, the best Arduino projects are the most ridiculous. Case in point, this motion-detecting squirt gun. The idea is simple: when it detects motion, the spray gun activates.

This Arduino-based Pomodoro timer project also uses this 25-minute cycle. Once you push the button to start the timer, it will run for 25 minutes, display a count-up timer and a "Study time!" ...
