SkittersSkittersA skitter is a one motored bot that reacts to a stimuli such as light, touch, or sound. Depending on how it is set up it ether turns on or off. They are also easy and cheap to build and can be built from techno junk sense there are no specific value the parts need. They can be solar powered or battery powered. Small or big. Or you could make a Halloween ornament. Its up to you!
The theory behind a skitter is very simple. It should have one motor, a sensor, a transistor,
capacitor, maybe a resistor, and some means to power it.
The skitter basically does something or stops something in reaction to the
arrangement of the parts. It can start failing about when touched, move when light hits it, move when there is no light, or anything else that you have a senor for. And depending on the motor it could roll, spin around, move like a turbot, or anything you can think of with one motor.
Skitter1:This skitter does nothing until the sensor is triggered. It uses a NPN transistor. You can replace the sensor with anything that will allow positive power to go through. You can play around with the value of C1 to get different timing effects.
Skitter2:Just a little more complicated than Skitter1 and uses a PNP transistor. It does the same as the above but in reverse. It stays on until the sensor triggers. R1 needs to be at least 100K or more. Play around with it until you get what you want.
