Hello everyone,
I am EXTREMELY new to electronics. I am trying to figure out how to put together an LED circuit that will be a part of a larger (non-electrical) hobby project I am building. The design is to have a total of 12 LEDs, 1 illuminated on/off push button. When the pwr is turned on, 4 of the LEDs and the illuminated button will light up and stay on. The other 8 LEDs will fade on and then slowly "pulse" or "breath". After MUCH frustration and countless YouTube videos, I have been able to breadboard a circuit to accomplish the pulsing effect on 1 LED. It's now time to figure out how to make everything else work correctly too. This is why I have respectfully come to your online community for help. If someone could figure this out for me, it would save me a ton of time and you would have my humble gratitude. I will attach a photo of what I have come up with so far. The area circled in pencil is how I got 1 Led to "pulse" on and off at the rate I wanted. Green indicates the LEDs I need to pulse and yellow shows the illuminated button and other 4 LEDs that I need to simply light up and stay on. On top of each LED I have place a small "1" or "2". This is because I will be using two types of blue LEDs. [Type 1: 5mm Blue, Vf=3.2, If=30mA]. [Type 2: 3mm Blue, Vf=3.5, If=30mA]. Power supply will be a standard 9V "square" battery. (But that can be changed if need be. ) THANK YOU so much for you time and any help/advice you can offer. Remember: this photo is just me putting something down. Feel free to do whatever you need to in order to make it simple and functional. -Cheers!
