Motor speed control

The OPB350 series liquid sensor is designed to operate with clear tubes of various outer diameters: 1/16 inch (1.6 mm), 1/8 inch (3.2 mm), 3/16 inch (4.8 mm), and 1/4 inch (6.3 mm). When integrated with output reference circuitry,...

The issue arises when connecting the 8051 microcontroller to the HT640 encoder; the data transmitted is not received by the receiver. However, when the 8051 connections are removed, the transmission functions correctly. This indicates that manual RF communication works...

For normal use it is necessary to connect the battery when the jumper is connected. Please take care that the transmitter is on and the throttle is set to "power off". More: * switch on the transmitter, throttle to...

Sometimes, for a variety of reasons, it would be nice to vary the width of the sound stage when listening to stereo recordings. Although technically this is anything but hi-fi, it is a useful addition to PC speakers, or...

The circuit illustrated in Figure 3-148 eliminates the requirement for a step-down transformer by utilizing a thyristor for brake control in small capacity asynchronous motor braking applications. Upon shutdown, the contactor KM1 releases, while contactor KM2 engages the brake...

This Low Dropout Voltage (LDO) solar charge controller utilizes a straightforward differential amplifier combined with a series P-channel MOSFET linear regulator, creating an effective synergy. The voltage output is adjustable and is primarily designed for charging 12V lead-acid batteries....
