Getting Control With the Propeller | Part 1
Recently, an artist friend asked me how he might go about automating his latest masterpiece using a BASIC Stamp®. After looking at what he had, it turns out he was going to need to control DC motors, hobby servos, and stepper motors. While there are solutions for controlling all of these devices it would generally mean having three separate controllers (one for each device). A better solution would be ...
Getting Control With the Propeller | Part 4 | Propeller Multi-Controller
This month, we wrap up our four part series by covering practical use of PWM on the Propeller using our multi-controller board. In last month’s article, Kevin McCullough covered stepper motor control and made schematics available on the project web page. These schematics use the L293D Quad Half-H Driver IC which provides bi-directional drive currents of up to 600 mA from 4.5V to 36V. We will use the L293D in this article for both motor control and light dimming...
