Need some help hooking up my hardware

Using Arduino General Electronics
#1

The issue I am having currently is setting up the hardware between my UNO , motor IC, DC motor, and RC batterty. I understand two signal cables go to the digital row of pins on the UNO and the ground jumper cables must be connected to the Arduino, but I need the RC battery power connected to the steering. The IC is able to take well over the power from the RC battery (which should be 7.2 on the RC). I don't know how to hook this up on my bread board due to inexperience with Hardware . I would also like to make an additional circuit for just the DC motor and RC battery first then make the connections for the IC to Arduino.

The IC is a NTE7042 Bi-directional motor driver Here's a datasheet link. http://www.nteinc.com/specs/7000to7099/pdf/nte7042.pdf

This for a RC project I'm doing, so far I have upgraded the steering servo and have a PS3 controller successfully communicating to my USB shield dongle via bluetooth.

If anyone would be kind enough to help it would be much appreciated.

The IC you are using dictates that you need to use a DC brushed motor, and you should build this circuit to make sure that it works and does what you want.

Here is how you wire it up the motor and the IC to test the circuit, connect (+) terminal of the motor to pin7 of the IC (-) terminal of the motor to pin9 of the IC battery (+) to VCC battery (-) to GND a 50K resistor from pin1 to GND a 50K resistor from pin3 to GND

To test motor spinning forward: connect pin3 to to VCC with a 10K resistor. To test motor spinning reverse: connect pin1 to to VCC with a 10K resistor.

Once you got this working , you can connect the Arduino to pin1 and 3 to control the motor direction as indicated in the datasheet Truth Table.
