Hi, i'm trying to work out the best way to make a circuit which will flash 2 LED's alternately at quite a quick speed. There are a few requirements though.
1-I need it to be as small as possible since it will need to fit inside a watch casing.
2-It should be able to run off a single 3v button battery.
3-This one is an option, but it would be good if you could press a button and have it flash for 20-30 seconds and then switch off. Alternately holding down a button to keep it activated would be Ok.
I've been reading through the forum and have read about different chips such as the 555 chip. I am guessing something like this would be required. I only have a limited knowledge of electronics, but my younger brother is doing an electronics course so if I get stuck on a few things he can help me. Any help would b appreciated. thanks
