Taking Things Step by Step.........................................................................

Creating your go-kart involves building the transmitter, building the receiver,

and then assembling the go-kart body with its motors and three wheels. The

receiver circuit gets mounted on the body as well, and then you top the

whole thing off with the plastic bubble cover.

Making the transmitter ......................................................................

The transmitter — the thing that you hold in your hand like a TV remote

control — is what you aim at the go-kart to control it.

Follow these steps to build the transmitter circuit:

1. Place the encoder IC, resonator, voltage regulator, resistor, and
   capacitor on the breadboard, as shown in Figure 11-7.
   Make sure you put the negative lead of the capacitor in the same bread-
   board row as the center pin of the voltage regulator and the positive lead
   in the same breadboard row as the +5 volt output pin of the regulator.
