Wiring up the bot

Now let's start making the circuits required to build our Bot.

Wiring L293D with motor

First we interface both the motor of car with motor driver IC L293D as shown in the following diagram:

Figure 8.7

In the previous diagram:

OUT1 (pin 3) has been connected to one terminal of LRM
OUT2 (pin 6) has been connected to second terminal of LRM
OUT3 (pin 11) has been connected to one terminal of RRM
OUT4 (pin 14) has been connected to second terminal of RRM
VS is connected to positive terminal of 9V DC battery
GND is connected to negative terminal of 9V DC battery

The OUT pins provide DC output voltage to drive the motor. The value of voltage output of out pins is decided by the voltage applied to pin VS...
