Wiring 555 IC as a Square Wave Oscillator for Two LED Flasher Application
Sponsored Links
After previously article discuss about 555 IC, the following article will provide you with an application kit – a two LED 
flasher which uses 555 IC Timer to be wired as a Square Wave Oscillator (astable operation mode). This application kit has a double ended output connection in which the LEDs will start to flash simultaneously ON and OFF when connected to a battery or 5V to 15V power supply.
The circuit diagram shown above perform how to assembly of the two LED flasher application kit. And these are the following component to be applied: 2 pcs 820R grey red brown for R3 R4, 2 pcs 1K brown black red for R1 R2, 1 pc Koa trimpot 100K 104, 1 pc ceramic capacitor 10n 103 (C1), 1 pc electrolytic capacitor 10uF (C2), 2 pcs 5mm re LED for L1 L2, an LM/NE555 IC, a 8 pin IC socket, and a 3138 PCB.
You are also provided with informations such an animation of what happens in this two LED flasher, or entering values for R1, R2, C and what flash rate would these component give. Follow complete read of Wiring 555 IC as a Square Wave Oscillator for Two LED Flasher Application in this 555 Application Datasheet (source: quasarelectronics.com).
