Are you a hardcore gamer?Playin adrenaline pumping games like MGS series,Resident evil,crysis,Lost planet etc?Do you want to show off your buddies how you are pumping your lungs?
Then this instructable will show the way for the right thing!
With this circuit you can drive leds from single led to hundreads of leds.Leds will fade in and fade out.It will simulate the breathing of gamer.You can also use it to make gostly eyes!!!!!!!!!!!!!!
Any one can build this.It is super simple.Requires few parts.It's heart is a 4 pin ic named ne555.555 is a ic that got 1flipflop(used in touch switch) and 2 comparators(op-amp).
I hope everyone will enjoy it
Step 1: Things you will need
3.470uf capacitor(White coloured cap in the diagram)
4.2n2222 npn transistor(upto 10 leds but for more leds it will need more amp.So for that 2n3055 is recomended)
6.100nf cap(not necessary)
Thats all we need.Lets make it.Lets Goooooooo!
Step 2: Building the gadget
After watching the diagram plz try to put all components by yourself it will help you on the future
