This is a great project to do with your kids, grandchildren, students, etc. It’s a small circuit that uses a battery to light up two alternating flashing LEDs. My kids who are five and seven loved working on it together in the garage. They enjoyed doing a project with dad, and learning about soldering and electronic circuits. They show their LED flashing circuit to everyone that comes to the house. So if you want something to do with your kids that involves some hands on ‘maker’ activity this is good for you. Also, if you have kids in a class or group of any sort such as scouts or summer camp and want a building activity, this project would be ideal for you.
