Homework Help: Building a circuit? - easy high school project sorta

    building a circuit?? - easy high school project...sorta

    Ok so my teacher just walks in one day (w/o any syllabus or assignment sheet) and tells us to build a circuit that would cause a lightbulb to flash on and off. He specified that the cicuit cant be made by buying something that was specifically designed to do this. According to him an oscillator and a timer is ok...i have no ideas what these are. I've been looking up oscillating circuits on google and it seems a bit too complex even for an AP level class. Can any help me get jumpstart on an idea (or just tell me what type of circuit one would build for this project) because I have no previous background on this at all :grumpy:

    Try a 741 opamp or a 555 timer. Go from there.

    I think that maybe a capacitor would do it in the right configuration too.

    Can you use a signal generator?
