The Traffic light controller circuit. use the LEDs for display and the digital circuit as based, include IC-4027,CD4017,IC-555 and so easy and cheap. [...]
This is a simplest slave flash trigger circuit. It will help the slave flash immediately works almost simultaneously with the main flash. This circuit better than others circuits because without the external power supply.
I like a Simple 2 Lamp flasher circuit using MOSFET. Also, it is Astable Multivibrator. When you want a high power lamp flasher. This is a better choice for you. Why!
This high power led flashlight circuit look like torch by 1.5V battery only so it can be used, small so Easy to carry in various places,also very bright [...]
This is a low voltage LED flasher or 1.5V LED flasher circuit using BC556 and BC546 transistors. And other electronic devices is 4 resistor and 3 capacitor
If you get the job From teaching science to electronics projects. Elementary education level. This project is right,as 10 LED roulette circuit using TC4011-LM4017. They uses the principles of digital…
