You can control the brightness of these LEDs using variable resistors VR1, VR2 and VR3 respectively. Parts Needed. Arduino UNO board – 1 ; 5mm LEDs Red, Green, Blue – each 1 ; 100K Variable resistor – ...

I had the idea of building this Arduino icicle lights project during the making of the light dimmer circuit and the result can be seen ... were used in another circuits so the result is not too ...

You have given your circuit no way to communicate with the arduino. 4. While each pin may provide 100mA, there is a chip limit so ALL pins can’t provide 100mA at the same time.

Features of the Arduino LED Matrix include : – Single-color 32 x 9 or 64 x 9 LED matrix display with several color options – ESP8266 controllable and programmable via Arduino ...

It is a pretty common first project to use an Arduino (or similar) to blink an LED. Which, of course, brings taunts of: you could have used a 555! You can, of course, also use any sort of oscillato… ...

Arduino, LEDs and Nixie Tubes? What's not too like? The Smart Nixie Tube is described as the first expandable Nixie Tube display with built-in Arduino Uno compatible hardware. Tyler Nehowig, an ...

Essentially, it is another safety initiative that gives a visual warning of a biker braking, with LEDs tucking up the end of the handlebars. It is based on an 3-axis accelerometer board, provided by ...
