H bridge switch for small motors
Two inputs, A and B, control the bridge. With both high (or open circuit) both ends of the motor are connected to 0v. Connect A low and Tr2 turns on causing the motor to go forward. Connect B low and...
Electronic pulse circuitry fishing
The circuit utilizes the SC3525A, a PWM silicon chip from US General Semiconductor. It features an error amplifier with an inverting input at pin 1. Pin 2 serves as the non-inverting input for the error amplifier. Pins 5 and 6...
Control circuit keeps dc motor running at constant speed
The purpose of this circuit is to maintain a permanent magnet DC motor at a constant speed, which is set externally. This is achieved by monitoring the current flowing through and the voltage across the motor's brushes.
The schematic for this...
Speed Control of DC Motor using Microcontroller 8051 withCircuit
The objective of this project is to control the speed of a DC motor. The primary benefit of utilizing a DC motor is the ability to modify the Speed-Torque relationship to nearly any desired form. To facilitate speed control, an...
isolated mains power monitoring arduino
A mains (220-240VAC) power monitoring circuit has been sought for interfacing with an Arduino. While the OpenEnergyMonitor solution employs a transformer for isolation and measurement of mains voltage, it has been noted that the transformer does not couple effectively to...
Pulse-Width-Modulated Motor-Speed Control Circuit
Connected in this manner, an LM317 1-A adjustable-voltage regulator can be utilized to control the speed of a miniature DC motor or to adjust the brightness of a small lamp. The circuit achieves this by modulating the pulse width, and...
