This project will be created for use with 2 LMD18200 H-Bridge ICs. These H-Bridges are capable of driving a motor with a voltage range of 10V-DC to 55V-DC with up to 3A continuous. It can drive the motor at a variable speed and reversible direction. It also has current sensing and thermal overload protection.DC motors can be controlled from the OOPic in a variety of ways utilizing everything from relays to power mosfets. This project shows how to configure two oPWMs and some oDIO1 Objects into a Virtual Circuit that will control the speed of two DC motors. with simple commands like M1Speed = 10 for a slow speed, M1Speed = 255 for full speed, and even M1Brakes = cvOn to slam on the brakes.[more]
One of the nice things about flying electric is you can test run your motor in the house, workshop, or in the yard and the neighbors won’t complain. The problem is how to control the speed of the motor. One way is to use the plane, radio, and speed control with the motor in it. That’s no fun! Mount the motor on the bench and just plug the battery into the motor. That’s even worse! It’s hard on the motor and gearbox. [more]
This project allows you to control speed, direction, and step size of a stepper motor. If you are interested in robotics, motion control, or just want to learn about this widely used motor in almost every electronic gadget like floppy drives, printer, scanner, robots, every device; then you should try building this versatile stepper motor control.This article also provides precious information about the basics of stepper motors, as there is not much literature spread out about it. It will help you go grasp the understanding, and control the MASTER MOTOR. You will also learn how to interact between PC and external devices, (PC interface through parallel port).[more]
This project was designed to drive the stepper motors on an equatorial mount for the purpose of astrophotography.The main complications in the circuit come from having two driven motors and from the necessity of having slow motion control on both axes. The circuit described here uses the Motorola SAA1042 stepper motor controller IC to provide the high current signals to the stepper motors. There is one SAA1042 for the polar axis motor and one for the declination axis motor. [more]
This serial servo control software was written in “Visual Basic 5 Pro”. It uses the PC serial port “com1″ to talk to a Basic Stamp, or a Pic Micro programmed with MicroEngineerings PicBasic.In between positions are available as well.You can just click on the slider and hold the mouse button down while moving the slider for large adjustments, or use the up/down arrows for slower more precise positioning.[more]
