>>5745050Here's one with a 555 timer, not mine the schematic, but I've use it in some projects if the arduino wasn't available (it's even easier with arduino but for what you wanna do it would be absurd). Change the capacitator value and led resistance to obtain different blinking paces. There are other ways to obtain a blinking led but this is one relatively easy and cheap, you will need a breadboard to solder on also. And always check if everyting works before putting it inside, if you have a test breadboard use it to see the blinking and how many leds can you feed. Also try not to solder the 555 directly and buy it a socket so you don't burn it while soldering and be easily replaced
