I have been asked to supervise a small workshop for total beginners during a science week fair.
They may be of any age. I will have to eventually put some limits there,
but this is to be chosen. They can be kids from 12 to 16, or adults.
The workshop will be in two sessions of 2 h during the same week.
There will be 20 attendees in 10 groups of 2.
A big constraint is the material. Ideally, it should be < 5 $.
I am asking here for suggestions as I never did that. I see two possibilities :
-A) I can go for pure electronics, without programming :
- a small breadboard, some leds, resistors, caps, 555, buzzer, transistor, wires.
- any suggestions for fun circuits ?
B) I can go for an arduino (ebay source) with usb plug and programming.
like this one

I will be very pleased to get any suggestions for possible circuits in both cases, especially if some of you
have experience in such performance.
