Hi 👋. I'm Richard Huf. I'm a Senior Frontend Developer, interested in design systems, CSS, accessibility, React, Typescript, and the open web.

Slightly more complex circuits

Here are a couple of circuits I've put together on the breadboard. I'm using a battery here, so that I can get a better understanding of the fundamentals of building circuits.

Working with a Raspberry Pi is interesting and all. But I found after a while, that programming a certian general purpose input output (GPIO) pin to go high or low, wasn't very satisfying.

It may be because I've one a bit of programming, that I'm not supe excited about that part of it. Which is why I'm going analog, or physical, for now.

Some videos of simple circuits

I'm using a battery here, rather than the raspberry pi. This has been helpful as it forced me to learn more about the fundamentals of electrical circuits. I've got a lot left to learn, but I'm enjoying it so far.

  1. Changing the color of an RGBLED with all the switches and potentiometers I could find at the time.
  1. A 555 timer Integrated Circuit (IC) to flash a red and blue LED on/off.

I've started learning a bit of soldering. I think the next project I'll work on will be to solder the flashing red/blue light circuit onto protoboard, and put it in a small housing.
