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 ...

Arduino controlled Christmas lights! It all started ... He uses an Arduino Uno to control them, and a 460W computer power supply to provide the juice. The LED modules themselves are Adafruit ...

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 ...

With each contact you make, the red LED lights up ... with only an Arduino UNO, ultrasonic sensor, force-sensitive resistor (or push button), and piezo buzzer. The tone generated depends on ...

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 ...
