An Arduino shield for driving LED strips!
How to assemble a LM3914 charge indicator board
This is a teardown of the IKEA TVÄRS lamp and provides two small but fun projects you can do with this very versatile, very affordable lamp from IKEA: a controllable RGB lamp and
I built a sunrise alarm clock in Arduino.
It starts to get messy if you want to add more than 3 LEDs to your project because each LED requires a pin. While there are one wire protocols that make this a
A trimpot is basically a resistor that you can vary the resistance of. This is useful for controlling output in an analog manner. The push switches only turn on for the length of
In your package you might have a tiny white chip with three wires sticking out of it. This is a 5050 LED IC. What this chip does is that it combines three small
You use LEDs everywhere, here are some ways to make them better. Ping Pong Light Diffuser Sometimes you got a really bright LED that you want to diffuse. A simple way to do
Blinking an LED is all fine and dandy, but it doesn't make for any pretty effects. A breathing LED, now that is something pretty to gaze upon. But how can we do that?
We will blink an LED again, except this time we will move it to to the breadboard. The difference is that we are connecting an external circuit to our microcontroller by giving one
So you have an ULCK set in your hands. Now what? Have you downloaded the Arduino IDE (required for programming) and followed the guide for board definition installation for the ESP8266, the driver
