Messing around with Arduino ... at all (LEDs won't light up or will be too dim, etc). Too much and things probably won't work right and also might short out and create a fire risk. Resistor ...

You can use Arduino's C-like programming language ... You should now have the "D13" wire, LED, and resistor in a pattern somewhat in the shape of a stretched-out "Z" (see photo below).

To build this DIY buzz wire game, you'd need an Arduino Nano, a 9V battery, two LEDs (red and green), a ... force-sensitive resistor (or push button), and piezo buzzer. The tone generated depends ...

So sensitive in fact, that a resistor of a ... would trigger off its own LEDs and buzzer, trapping itself in a never-ending loop. [Mirko] solved this by encasing the Arduino inside a closed ...

LOW); // set the LED on The Arduino Micro is closely related to the Leonardo, with some small difference. Each led in both is connected in series with a 1kΩ resistor to limit current. One ...

[Computergeek] made an Arduino Shield in order to use ... he should probably have invited a resistor to the party the two IR LEDs are having.

There is so much you can do with WS2812B addressable LEDs once you learn the basics. However, always remember to choose the correct micro controller (or arduino board) based on the RAM requirements of ...

Is not a complicated project so it can be done easily by anyone who has an Arduino board or an Atmel microcontroller with bootloader on it. I have used red LEDs because at the moment the white and ...
