$150 Robot - Build the Circuit

Part 7 - Build the circuit

Some people say breadboards, some people say solder your board. I think breadboards are fine unless you want you robot to be permanent, but if you might ever want to recycle parts stick with the breadboard. That's why we chose small cheap boards. Eitherway you will want to make your first draft on the breadboard.

Here's the schematic that's used for the $50 robot (which is really what we're building)

Basically we need:
power - input, voltage regulator with capacitor, led, power switch (optional)
sensor inputs - 3 pin headers that have vcc, gnd, and pin to the microcontroller (pins 27,28)
servo inputs - 3 pin headers that have vcc, gnd, and pin to the microcontroller (pins 2,3)
microcontoller - use the ic socket (especially if you are soldering)
we don't need the program header because we won't be programming the chip on this board
