Arduino Motor Shield

Utilizing the ATmega 2560, which serves as the core of the Arduino platform, a universal remote control with GSM capabilities has been developed. This device allows for the control of 2 inputs and 2 outputs, DTMF key functionality, gate...

One of the most interesting shields that can be mounted on the Arduino platform is the Ethernet shield. It enables numerous networking applications such as remote control of systems and users, web access, and data publication. The ease of...

FIG T is the excitation transformer, R is a varistor, and there are rectifier diodes to protect against breakdowns from VDii to VD16; Rz and C2 provide resistive-capacitive protection. The circuit is designed to absorb voltage from the magnetic...

Most battery motor speed controllers are under manual control and the operator automatically adjusts speed to match demand. Under these conditions closed loop motor speed control is an unnecessary expense. However, when it is required, a tachogenerator can easily...

This is a simple and easy-to-construct circuit designed to provide a bidirectional drive for a DC motor. The circuit operates straightforwardly. The output of an astable multivibrator based on IC1 (NE555) is utilized to control the relay RL1 that...

The modification of a basic speed control circuit for small DC permanent-magnet motors implements a maximum current limit during normal operating conditions and a reduced current limit during stall conditions. This design aims to limit the dissipation of series...
