Here is a simple Arduino Camping Light project ... This part number (and ofcourse the LED type) is not very critical. If you want to use a bi-polar transistor, don’t forget to add a resistor (~1KΩ ) ...

It works like you’d probably expect — the light moves back and ... Inside the cool laser-cut box is an Arduino Uno and a 9V battery, plus a current-limiting resistor and the all-important ...

First, upload the following PWM sketch to your Arduino Uno r3/Nano v3 and connect a 10mm water-clear green LED to D9 ... a 220Ω-470Ω resistor and cathode (K) to GND. #include <SimpleKalmanFilter.h> ...

This translates into dimming and brightening of the light bulb. If you want to try this out using a resistor and an LED, here is a simple Arduino UNO Sketch that will dim and brighten the LED in ...

Powered by an Arduino Uno, the light painter provides a user interface on a 16×2 LCD which allows control over not only the brightness of the WS2812 LED strips but selecting and loading different ...

The helmet is equipped with LED lights that are controlled by the Arduino Nano. When the motorbike’s indicators are activated, the Arduino Uno sends a signal to the Arduino Nano, which then ...

and brake lights to keep you safe. The entire system is built on the backbone of an Arduino Uno with a few other parts totaling at about $150. That seems expensive, but DeBoisblanc's build covers ...

Arduino has launched its next generation of UNO boards, introducing a 32-bit Renesas microcontroller and Espressif ESP32-S3 module, one-click cloud connectivity and plenty of I/O plus a 12×8 red LED ...
