How to rotate dc motor in both direction

It is easy if you control DC motor in a single direction. Sometimes you think. How to rotate DC motor in both direction. You are not worried. There are many ways to control speed, on-off, and dc motor reverses rotation. In these circuits below use many types of components, power transistor, MOSFET and Relay. The input of these circuits may be low volt of DC pulse, digital circuits, Arduino, and more. 2 channel DC motor driver on saving a model This is 2 channel DC motor driver on saving the model. Using transistors as main components. They can control rotate…

Touch Motor Control by SCR and Schmitt Trigger

This circuit designs for control DC Motor 12 volts. By use the touch on the plate, the Motor as a result turn go to once. When use a finger touches the metal plate makes Schmitt Trigger Circuit (by IC-4011 nand gate CMOS) take a signal from Oscillator Circuit and make a signal goes out to bias current a base of Q1-2N5088 works and then it will be trigger a SCR1 to drive the DC Motor 12V then turn follow want. - For power supply type of DC Motor this must be AC current 12 Volts Only. Because of make SCR…

ULN2003 Control Stepper Motor by Parallel Port

This is an easy to build stepper motor driver that will allow you to precisely control a unipolar stepper motor through your computer's parallel port. With a stepper motor you can build a lot of interesting gadgets such as robots, elevator, PCB drilling mill, camera panning system, automatic fish feeder, etc. If you have never worked with stepper motors before you will surely have a lot of fun with this project. But This Stepper Motor Controller Connection Diagrams use 2 port voltage are 5Volt and 12V and four resistors , a zener diode. The Four-Wire Connection the ULN2003 (High-Voltage High-Current…
