There’s such a massive number of simple circuits out there that it is hard to keep track of, and remember them all. I think a collection of them will be helpful. Diagrams will be changing pages as I add more.

Single components and multimeter measurement:





Kit that has everything you need to learn basic electronics and Arduino.

Resistor basics

Resistor component





Breadboard that I use. I really like it! I’ve damaged a few holes but it has lasted a lot longer, and the components insert better, than the cheap boards I’ve used.

Common multimeter measurements

001 Resistive component multimeter voltage-current-resistance measurements

Resistor limiting current – Ohms law

Simple circuits and fragments:





Nice looking LED kit. Good to have a lot of LEDs because it’s relatively easy to damage them, or to want to use a lot of them in various projects.

007 Parallel components – Resistors – Light emitting diodes LEDS – Capacitors

Polarity indicator





The ad above is to a best selling multimeter since the ones I use are unfortunately not being sold anymore. It still helps this site if you click the link, check out the meter and compare it with other meters to see what looks best for you!
