555 Timer LED Fading

https://circuitdigest.com/electronic-circuits/fading-led

Im not good at electronics and wanted to make this circuit but i need it to power 3 led's instead of only 1 led. Can i just parallel the led or i need to change anything ?

thanks

Connect 3 in leds in parallel

Yes, you can connect 3 LEDs in parallel, it will works. If in case you will not get enough intensity, then just decrease the value of R2 resistor across LED to approx 300 ohms.

Parallel connecting is ok

You can connect the leds in parallels.

The slow fade led circuit is
July 31, 2020 - 4:59pm

The slow fade led circuit is very simple, 555 has been used in Astable mode and a transistor is used to amplify the current. In Astable mode 555 IC oscillate at a particular frequency, means output at PIN 3 goes HIGH and LOW periodically.

Need an idea to built an led blinking circuit
August 3, 2020 - 11:08pm

I need an idea for a led blinking circuit which has 2 inputs. When giving input 1, it should blink for 5 seconds and while giving input 2 ,it should blink for 10 seconds .Please suggest me some idea ASAP

Hii Deepaa

You posted the question in wrong place. However, You can use RC time constant circuit to achieve this one where you need one NPN and one PNP transistor. Use two different time constant two achieve two different time variables. Hope this will be helpful for you.
