A chemical mixer circuit equipped with stirring speed control, a thermostat, and a timer alarm function is suitable for use in the chemical, steel, and other industries. The circuit includes components for heating, magnetic stirring, motor control, and timing...
A simple circuit is required to simulate sensor inputs to a PLC. The sensors operate at 12VDC and output a current of 4-20mA. The XTR series devices are being considered for this application, but clarification is needed regarding which...
CMOS switches are utilized to select entries in audio circuits. While these switches can introduce unacceptable levels of distortion, incorporating them into the feedback network of an operational amplifier (op amp) can effectively minimize this distortion. The circuit employs...
This is the second part of a USB tutorial for the ATtiny2313 microcontroller and the V-USB library. The first part covered how to derive 3.3V from USB to power circuits. In this section, the setup will be expanded with...
The introduction for a unidirectional thyristor trigger circuit is also applicable to the TRIAC. Various configurations are presented in Figure 16-28. Figures 16-28 (a) and (b) illustrate a direct trigger circuit; Figure 16-28 (c) depicts a dual diode trigger...
The 4046 PLL serves as the core component of a tunable ultrasonic receiver designed to detect inaudible ultrasonic sounds. This receiver can also be utilized in conjunction with a basic ultrasonic generator to transmit and receive Morse code. The...
