A few months ago we brought word that [Electronoobs] was working on his own open source alternative to pocket-sized temperature controlled soldering irons like the TS100. Powered by the ATMega328p … ...

The backbones of operational amplifiers are the integrated circuits LM358 and OPA2182, which are available on the market. Both have distinctive features, and their use is tailored to the needs of each ...

So to overcome these situations, I have come up with an arrangement consisting of an Op-amp, MOSFET, and Arduino, through which I was able to change the gain of the op-amp programmatically. So, in ...

The reference voltage can be adjusted using a pot or variable resistance. Regardless of which way the voltage divider network is paired with the OP-AMP, the output logic can be used to make light or ...

Operational Amplifiers (Opamp) has so many interesting applications, and we have already created many circuits using op-amps.Today we are going to study one more application of Opamp which is to add ...

Texas Instruments' LM358 devices, stocked by Digi-Key, consist of two independent, high-gain-frequency-compensated operational amplifiers designed to operate from a single supply or split supply over ...

This article presents a simple circuit to convert transistor-transistor logic (TTL) or pulse width modulation (PWM) signal to analogue signal using LM358 operational amplifier. The circuit can be used ...

Wanted to generate a LED fading effect (fade-in and fade-out) for my upcoming video tutorial using the 555 timer IC. I already have a video where I used LM358 Dual Operational Amplifier IC and another ...
