If you don't have the physical components, you can simulate this project using Tinkercad. Create a new Tinkercad account if you don't have one. Create a new circuit in Tinkercad. Add an Arduino UNO, ...

Recall the last time you tried to dim an LED using pulse width modulation. I am sure you have experienced the relationship between the duty cycle and the perceived brightness is not linear at all. The ...

Being able to use one of your old projects to make a new one better can be quite satisfying. [Steve] from Hackshed did just this: he integrated an Arduino based webserver into a new network control… ...

Arduino is a well-known open-source electronics platform that provides users with the ability to create interactive and easy-to-control systems in a reliable manner. A popular use for Arduino boards ...

The Icoled lamp is a fascinating blend of modern technology and creative design. The lamp’s structure is composed of multiple 3D-printed components, which include 5 and 6-sided knotted pyramids.

In this last step of getting the project working, connect the LED to the D7 pin of your NodeMCU. The 330-ohm resistor in series (as shown in Fig. 12) is used to limit the current through the LED. Fig.

Inside each box goes a colored LED, wired back to the Arduino. For the software, [Will] is using a floating analog pin as a source of random noise, and from there comes up with how often each LED ...
