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...
