Arduino: How to make your first robot with..

fritsl — Mon, 08 Sep 2008 07:25:10 -0400

When writing this, LMR only offers "Start here" - instructions on how to make your first robot, using Picaxe.

"Nebster" wrote to me, and asked if I could do a parallel, using Arduino, and I think that is actually a very good idea (now that Picaxe refuses to pay me commission, haha)

Focus should be on making first timers get a robot up and running at a low cost, and most importantly learn how to hook up motors, a servo, and a analogue input in "no time".

L298 Compact Motor Driver Kit

This is a motor driver that I like because of this:

It is usable from 6 to 50V, at up to 4A total output current
It has a 5V output, so you can just hook up any battery (above 6V), and then hook your Microcontroller up to this motor controller
It has LED's to indicate that the motors (should be) going

it is controlled by setting pins high and low, and that is..

Relays (DPDT)

Relays are an alternative to motor-controllers.

They do consume a little power from your battery when in either on or off position (turned on) - but they also do deliver the full power that you want - where a motor-controller often takes some of the power (voltage-drop).

They can be found to be able to handle much more current than a motor controller matched in size (and price).

Pololu Micro Dual Serial Motor Controller

TheCowGod — Wed, 09 Apr 2008 12:35:00 -0400

This tiny module can control two motors, 1 A peak each, and you can daisy-chain multiple units to control up to 62 motors with a single serial line. The new version provides up to 2 A to a single motor, or 1 A each to two motors. The motor supply can be as low as 2 V, making the unit a perfect match for small DC motors. Using one serial output from your microcontroller, you can independently set each motor to go forward or backward at any of 127 speeds, coast, and brake.

The controller takes up almost no space on a breadboard or PCB:

Very serious shop if you are looking for a (serious) motor controller, Tamiya set or similar..
