I ordered 20 cheap (what I thought was) slow flashing LED’s. To test them quickly, I hooked them up to my breadboard, threw in 10 resistors, and wired them all to the same + and – terminals of 4 AA batteries. I’ll explain how all this works in a different post, but this is just to show that by taking 2 minutes of your time, you can have something relatively good looking set up!
