I'm really inexperienced when it comes to electronics, and have only very basic knowledge and have done close to nothing by hand. What I want to do is to design a circuit for a 'buzzer round' of a quiz competition. Now normally, this involves just pressing the buzzer and a sound being created. Firstly, instead of the sounds, I want to use bulbs, which again, is pretty simple. Now, what I want is that, when two people press the buzzer simultaneously (as in, simultaneously to the human eye), only the bulb connected with the buzzer which was first pressed lights up. This is to avoid confusion when two bulbs light up at the same time. Can anyone help on how to go about this?
Secondly, I was also wondering if you could give me a few ideas for projects in electronics for kids (12-13 years old). Anything which would be interesting and challenging and yet, at the same time, not too difficult.
Thanks a lot.
