Some folks have gotten a 16 x2 LCD with a WiShield (WiFi) from Asynclabs working, but I am not one of them . I believe I had a pin conflict issue. a standard 16 x 2 doesn't use a shield, just a lot of pins.
Thanks for the comments everyone. I think I'll try ATiny and will definitely check out those Forest Mims books. Any advice on how to program an ATiny? Can I just stick it on a breadboard? Do I need a special cable to program it?
I currently have a curcuit with the following setup. A motion sensor triggers a row of 5 leds to light up. The light only comes on if it is dark enough thanks to a photo cell. All of this is handled through software and the Arduino.
Not knowing enough electronics juju to design my own circuit, is it possible to do soemthing similar without an Arduino?
Basically I want a small circuit that triggers a light to come on at night based on detecting motion.
