This is many LED flasher circuit and with PCB layout using transistors astable multi vibrator as low frequency oscillator below more...[...]
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.
How to reduce voltage for LED and others loads. We use a limiting current resistor reduce current or voltage in a series circuit. So easy to do
Why project does not work? Sometimes solder joint is bad. You need to know How to solder a circuit board. Easy but have to practice!
To Learn Relationship of voltage current power and resistance with water flowing so easy. Look at Ohms Law, basic electricity you should know.
First time for learning how to use LEDs.
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.
