If electronic Projects do not work. Sometimes solder joint is bad. You need to see: How to solder electronics for beginners. Easy but have to practice!
I’m teaching my children with basic Electronics Learning and Simple English. We will understand the working principle of electronics Components, Wiring, Basic Circuits.
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, the most article on this websites is hard to understand. We are sorry!
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.
The simplest constant current source that use a small IC only. See more!
We normally use this IC OP-Amp in voltage comparator circuit. Learn it more!
The LM324 circuit is high popular, in many circuit diagram,package of four (OP-AMP) The power is single-polarity positive- negative, very wide range. [...]
