Some weeks ago I got some Adafruit NeoPixel, a compact RGB LED module. Each LED module has a WS2812 chip that only needs three wires: power, ground and data. The data protocol is self-clocking, at a rate of 800KHz. The LED modules can be chained to build longer LED stripes. (For more details see the […]
Earlier today I’ve been following the Arduino Tutorial for driving a 74HC595 shift register which turned out to work pretty well.
In short, a shift register is an electronical component that can be controlled using 3 wires to change the output of 8 pins, or even more when two or more shift registers […]
I’ve been very busy over the last weeks, but now I’ve taken some time to get deeper into the “core electronics part”, which simply means that I got a breadboard and some electronic components like resistors, transistors, LEDs and a lot of wires.
The first step was to get a normal LED on the breadboard […]
