The buzzer is connected to the pins that are marked ‘BZ1’. R15 limits the current to a safe value (< 20 mA)." When assembling the circuit in an enclosure, Giesberts explains, you must be sure to ...

“The LED may also flash when the E and C leads are switched, but the flash rate will be faster,” Gerbig explained. “This reflects the fact that some types of transistor will operate with their emitter ...

For a player with such a Willy Wonka sensibility when it comes to pedalboard curation and his electric guitars, the Double Down is as simple as it comes – and yet it is a very clever twist on the ...

Fig. 1: Author’s prototype for mono AF amplifier Circuit and working Circuit diagram of the simple amplifier, which is built around audio amplifier LA4425A (IC1), is shown in Fig. 2. Fig. 2: Circuit ...

Circuit simulations are great because you can experiment with circuits and make changes with almost no effort. In Circuit VR, we look at circuits using a simulator to do experiments without having … ...

Sometimes we use a Preamp Circuit in circuits for pre-amplification of weak signal when the audio source sound level is too low. Pre-amlification of low level signals is necessary before feeding them ...

In this paper, a technique for slew-rate (SR) boosting suitable for switched-capacitor circuits is proposed. The proposed technique makes use of a class-B auxiliary amplifier that generates a ...

In Seemingly Simple Circuits: Transresistance Amplifier, Part 1– Approximating Op-Amps, the op-amp was approximated from a single-pole, finite gain amplifier to an infinite-gain, single-pole op-amp, ...

Maybe you are familiar with the op-amp as an extremely versatile component, and you know how to quickly construct a huge variety of circuits with one. Maybe you even have a favorite op-amp or two f… ...

This intercom circuit based on IC LM380 audio amplifier requires very few external components. So the circuit is very easy to assemble. Intercom circuit Circuit diagram of the intercom is shown in Fig ...

Circuit Explanation: Circuit Diagram of this Smoke Detector Project is given below: In this circuit, we have used an MQ2/MQ6 Smoke Or Gas Sensor Module for detect smoke present in the air. A BC547 NPN ...
