Adjustable Single/Dual LED Flasher Using 555 Timer IC

[@CrazyCoupleDIY]

In this tutorial, I'll first blink "an LED" using the positive pulse generated by a "DIY 555 Pulse Generator Module" (video: kzbin.info/www/bejne/mH6kn5ymhbSdfNE), followed by "two LEDs" alternating and flashing at a regular interval. The output frequency of pulses can be adjusted using a potentiometer. The circuit can be operated from any voltage between 5 to 15 volt DC. Watch this video for detailed step by step instructions on how to build this circuit and for a complete instruction on how the circuit works.

big fan sir

[@CrazyCoupleDIY]

Thanks a lot

Nice video, dont suppose you feel like trying out the Wein Bridge Osilator circuit next. I got it working perfectly at 50Hz on a breadboard now once I made the PCB I cant get to to be stable. Annoying thing.

I actually have a video on what you are after kzbin.info/www/bejne/eKiUYpydmryfe6M

[@caharparium2185]

how can I order pcb with the same model you use

[@CrazyCoupleDIY]

You can order from the pcbway's website Let me know if you want the link

[@caharparium2185]

send me the link. I want to order with the same module you use.

PCB way must have changed their prices because I downloaded the Gerber sent it to PCB way paid approx $11.00 dollars but then received an E-Mail to say i had not paid in full and in fact the price was $98 dollars and only for FIVE boards. I think you should adjust the Gerber or ask PCB way why it is so expensive. I was told on chat that the file did not meet the $5 criteria.

[@CrazyCoupleDIY]

If you don't mind plz ask them if they are charging you for individual breakout boards on a 100x100 assembly.

[@stuartpreston9018]

​I chatted with them and it was the fact that the boards did not meet their $5 criteria. I have a copy of the order etc but don't know how to attach it to this message. Not getting at you because the board is a great idea, just a shock at the price! @@CrazyCoupleDIY
