A wide variety of toys and electronics operate on TTL. For example, you could take an Radio controlled toy car or microav and control it via an Arduino. |

If you felt like a challenge, you could try and display different types of data with only the on-board LED. Someone out there made a single-LED voltmeter. If you had an old alarm clock laying around with an LED display, there's a lot of blinky fun. Carefully extract out the LED display, look for a model number and get the data sheet; or probe the pins with 2V to learn how to light up each segment. Plus there would be a buzzer or speaker you could make use of as others have mentioned With a light-dependent resistor and a speaker or piezo you could make one of those hand-held things that made noise when waved around on an alien surface in the original Star Trek show If you had a model train set, using a few cheap relays and some resistors you could computer-control track sections just like a real railway Appliance remote control could be done for under US$20 [self-promo] if you were willing to spend US$25 or so you could follow the first five chapters of my Arduino tutorials. |
