Hi guys i am very new to all this and want a simple circuit that will replicate the starting lights of a formula 1 race for my sons scalextric. So i have 5 led's and a 1.5V battery. I know how to connect these even with a resistor ! but thats about it. For those of you not aware of the F1 start, I require the lights to come on in sequence at 1 second intervals and stay on until the fifth light is lit when this is lit i then need them to all go out ideally with a random pause between 1 and 3 seconds but if thats too tricky for me then just a standard 1 second interval will be fine. The other thing is that i would like this to be cheap, at the moment my parts cost under 50p I don't want to be buying £20 parts! Also if there is something premade i can just wire into the system that would be great. The other issue i may have is that i don't fully understand circuit diagrams, i'm fine with basic electrics but not electronics !. I you could point me in the right direction for simple explanations that would be great.
