Hacking the IKEA TVÄRS Lamp for IoT and other Shenanigans

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 a lit charging station. Disassembling this lamp is pretty simple! First unclip the bulb holder from the

Just pile it on (More LEDs) (12)

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 much simpiler task, what if you really really wanted LEDs in your project? Well one solution would

Trimpot and Switches (6)

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 time they are pressed. The switches are connected across adjacent legs, which is laid out in the

One Wire Protocols (5)

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 but bright LEDs into a neat little package and by using some clever signalling, these LEDs can

Ping Pong Light Diffuser & other LED Improvements

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 this would be to take a white ping-pong ball, preferably dented, and using a small screwdriver, punch

Breathing an LED (3)

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? A microcontroller only knows two states, HIGH and LOW, how can we get a state in between

Breadboarding (2)

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 of the pins an output signal (much like how everything is run). This is important for two

Blink, blink. Hello World! (1)

So you have an ULCK set in your hands. Now what? Have you downloaded the Arduino IDE [https://www.arduino.cc/en/Main/Software] (required for programming) and followed the guide for board definition installation for the ESP8266 [https://github.com/esp8266/Arduino], the driver installation for the Arduino Nano
