speed control - Circuitos electrónicos

speed control
Sometimes you want to slow down a brush type DC motor. The most efficient way to do this is with a pulse width modulation (PWM) technique. The hobby corner circuit below can operate from about 3 volts to 15 volts. .

DescriptionThe 555 is ubiquitous and can be used as simple PWM speed controlCircuit DiagramCircuit Explaination: 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 .......

This circuit takes advantage of some new vertical cavity surface emitting lasers (VCSEL) that dont require light output control circuits. The circuit shows how to drive the device from a single high speed CMOS IC. The circuit can easily be modified to transmit signals from kilohertz to about 50MHz.

Circuit DiagramDescriptionThis circuit is a Digital Radar Speedometer. It allows us to evaluate the speed of any object moving, especially cars and other vehicles. The speed is calculated in kilometers per hour (KPH). Its display has three digits. This radar works with the laser reflexion. It sends laser radiation to the object and this object reflects t.......
