How to Control a Stepper Motor Using a Computer. Stepper motors produce accurate, computer-controlled motion for applications such as robotic arms and paper-feed mechanisms for printers.

Here, we can use two stepper-motor designs consisting of a stepper motor, the specific gage’s sensor, and a SoC microcontroller. Through the sensors, the SoC tracks voltage, current, or frequency.

To program these chips, [Aaron] first had to wire up the microcontroller into a circuit. This was just a bit of perf board, a resistor, a few caps, and a USB A plug.

Follow these steps to program your Subaru garage door opener without a remote: Find and press the "Learn" or "Smart" button on your garage door opener motor unit.

Programming means understanding how code interacts with actual computer hardware. If you want to get a visceral (and fun) understanding of programming, start with an Arduino.

The ESP8266 is the answer to “I want something with Wifi.” Surprisingly, there are a number of engineers and hobbyists who have not heard of this chip or have heard of it but don’t really ...
