Standard DC motor control can be tricky enough if you are new to electronics, but how about wireless dual dc motor control? A while ago I introduced you to a simple dual dc motor control design that used the SN754410NE IC to control some off-the-shelf 3v or 6v motors. Let’s take a look beyond just motor control and see if we can’t make that same system wirelessly controlled.
This article will explain how to build a dual DC motor control system, combined with a wireless receiver and transmitter which will tell the motors at what speed they should move forward, or backward. We will use standard and widely available parts so that anyone can follow along.

One of the basic aspects of robotics involves being able to control any type of locomotion. Motor control, through digital electronics, has become widely regarded as an accurate and well developed area and while many mysteries still remain, an equal number of motor control methods exist. The most simple of which is known as the H-Bridge.

I salvaged several of these motors from some Xerox inkjet printers. The motors were labeled well and I found manufacture specifications on-line. I was not able to find a wire diagram so I defaulted to making a truth table as I had done for unipolar steppermotors. Most steppers with 4 wires can usually be identified as bipolar stepper motors, which can be driven with a dual H-bridge IC such as the SN754410 by Texas Instruments. [via]
