First time for learning how to use LEDs.
I’m teaching my children with Basic Electronics Learning and Simple English. We will understand the working principle of electronics Components, Wiring, Basic Circuits, DIY, TIPs, etc. In simple ways!
For we can build mini electronics projects for example power supply, Flasher, light controller, times, solar cell. We are very happy to share what we learn with our friends.
It is true that the more you share, the more you know it. My English is very poor, most articles on this website are hard to understand. We are sorry! I will improve them.
Because we do not speak it every day. It is not our primary language. But we will try to learn English. So that everyone will hopefully benefit from it.

My son want to make a simple DC voltmeter on 0-10V range by Convert a galvanometer to voltmeter.Galvanometer DC1mA is cheap and easy with one resistor only.
The experiment on the simple series circuit. To understand current flow and voltage across all devices in the circuit.
To increase current transformer on the power supply. To save money with this idea, just only change connecting of on original transformer windings.
Here is a DIY resistance decade tool for testing and calibration. Because it can substitute into a circuit with all standard value. This ideal is cheapest that use resistors and wires only.
