  • Control DC and stepper motors with L298N Dual Motor Controller Modules and Arduino

    This board is only designed to run bi-polar motors. For uni-polar stepper motors, you must use a driver with the ULN2003 chip.

    No. You will need one driver board for each stepper motor. You can run two DC brushed motors from this board however...

  • Building your own CNC router/milling machine

    This is a really clean and concise article. Nice build, and nice authoring. As a new hobbyist, I would have really liked to learn more about the software side of running these machines. I have googled much about it, but there seems to be a ton of different options. Regardless, nice work on this build.

    BYJ48 Stepper Motor

    That is cleaner code. It works as planned, and it's easier to understand and execute; especially given the proper use of comments. Thanks for posting it.Any thoughts on modifying it for use with a pot? Basically: 'sweep with pot position'... I can't find clean code for this really anywhere. Especially with this specific hobby stepper.

  • RC Control and Arduino: A Complete Works

    Hey man, super cool that you wrote me back. I am totally new to the Arduino and Instructables environment; but I have been in r/c for 20 years (helicopters). Funny thing is, I have two UNO's and two WickedDevice 4 motor shields. I was getting some input from a moderator on that site today and when I tried to morph a small code sample he sent me (via Github); I blew up the UNO and two (out of six) servos. Seriously they caught fire and smoked my basement up. Haha. Here's the link to that string. http://help.wickeddevice.com/t/motor-shield-servo-set-up-sketch/107 I guess you could say they certainly did not play nice. Lol. I'm calling it quits for the night but tomorrow after work I will compose a writing that explains why I even needed r/c servo override functionality in the first place...see more »Hey man, super cool that you wrote me back.

Again, I appreciate your input and collaboration. Cheers.

    I really just need a straight forward, easy to understand "R/C -> Arduino -> Servo" sketch. No matter how much I search, the results are convoluded. Even this article, although very cool and creative, goes on so many tangents I can't follow the concept, or use the basic parts. I'm new to Arduino and feeling really stupid right now. Can anyone direct me to a sketch that is as simple as: Wire the receiver, controller, and servos-upload this code-use. Please, I'm begging for help. In the meantime, I promise to keep studying my "Arduino Starter Kit" and learning the fundamentals. Thank you.
