I have a Chemetron wirefeeder that I am using the motor and I want to use the speed control out of the control box to control the nice motor it had in .... -
That motor is rated for 6W which is 0.5 amps at 12V. I would use a 12V DC power supply rated at 1A or more. Any type will be OK. A plug-in adapter.... -
Hi Guys, first post to the forum here. I`m having a strange issue using an Intersil HIP4081A H bridge driver IC. I have it hooked up to an Arduino MCU .... -
After dismantling chinese copy of segway I wanted to check how the controller is made. After a couple of hours of work with multimeter, pen, a sheet of paper and Kicad I came up with a block diagram and schematic of motor controller. This motor controller is.... -
This motor speed controller uses a single IC LM1014 to control the speed of a DC motor. It senses the increase in the motor-current when the rotation of th.... -
This is the simple basic design of servo motor controller with pulse generator. It uses the CMOS IC 7555 in the Astable mode to generate pulses to drive th.... -
This simple micro-control circuit controls a servo motor according to a 3-state switch. A servo motor acts as an actuator in 3 position. It has 3 wires, one for VCC, one for Ground and another one for position control. The last signal is a single pulse with.... -
We are using 6v/2amps 1. 8degree stepper motor. In this circuit CD4050 hex buffer using to connect to the microcontroller. The output of cd4050 is connected to the TIP122 of the BASE. The Emitter and collecter is conneted to 1N4007 diode the colleter of.... -

Wireless stepper motor speed control project using laser and IC555. Read to know about basics and circuit construction using a wireless stepper motor which has speed control through laser and IC 555 .. -
This tutorial explains how to read the content of the microcontroller `s flash memory. The source microcontroller reads the content of the memory and displays it on the LED s. The content is nothing but the program written in the memory of microcontroller..... -
This page describes how I have modified my SkyWatcher dual axis EQ5/EQ4 motor controller to allow autoguiding through the parallel port from a PC. The modification allows the RA+, RA-, Dec+ and Dec- buttons to be activated from the PC via the parallel port.... -
A better way to make a stepper motor controller is to make a printed circuit board, and then simply drop the components in. After making the PCB, placing the components and soldering them hardly takes any time at all, in contrast to the proto board which.... -
The 555 Ic is wired as an astable and the frequency is constant and independent of the duty cycle, as the total resistance (R charge + R discharge, notice the diode) is constant and equal to 22Kohm (givin a frequency of about 1Khz, notice the hum). When the.... -
This article was previously published at, but I`d like to spread the idea further, possibly sparking new ideas in some of you, so I`m releasing it here too. My old partner and I were working on an improved version, using an ULN2803A instead of the many.... -
This is a very good integrated circuit. There is no need for any external glue logic to drive the circuit, there is only 2 pins to drive the motor, one for controlling the direction and the other to trigger the stepping pulses. It provides a very compact.... -
Despite the high impedance of its inputs, Darlington Q10 develops enough current to drive an LED. The inverted output of Q10 drives opto U5`s internal LED. Opto U5 couples to motor-control triac CR1. Motor Voltage Control Triac CR1. Triac CR1 is a.... -
This kit was designed to control the speed of AC motors with carbon brushes, anything from drills to saws to vacuum cleaners. Unlike other circuits such as normal dimmers the kit performs a phase cut only once per period. The moment of cutting determines the.... -
This is an implementation of the L298 to drive motors and inductive loads up to 4A continuously. Initially the L298 contains two separate channels, each one capable of driving 2A loads. Connecting them in parallel as in the schematic makes a single 4A....

This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of.... -
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is.... -
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to.... -
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This.... -
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the.... -
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,.... -
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the.... -
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power.... -
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
