Electronic beginners, enthusiastic ones generally know that the first spark sparking (amp circuits, etc.) or Light (led effects, etc.) applications attracted the person personally began with a startup my friend began to see the amphitheater circuit 🙂
Most of the LED circuits are simple transistors, 555, and logic door integrals. Two-color led burning circuit, LED flashers, RGB LED applications, LED gaming circuits and more: ready-to-be-calculated calculation of the resistance to be connected to the LED, LED calculation, information about the connection modes of LEDs, will be useful in schematics.
