Introduction In the previous tutorials, we talked about the inverting op-amp and non-inverting op-amp, we considered configurations that take a single input on either pin "-" or "+" of the operational amplifier, while the other pin is grounded. However, it is possible, as we will see...

In Sayanee's Basu's video, we can look at the design considerations in the process of taking a breadboard prototype to a custom PCB, from the microcontroller to the various subsystems, to the power, the bootloader, and even how to deal with faulty components. A breadboard can be...

Introduction The previous tutorial about the non-inverting operational amplifier has shown all the details of this op-amp configuration that takes the input signal on the non-inverting pin (+). This could be done by studying the ideal and real models and demonstrating all the important...

This is a Type K Thermocouple Sensor Amplifier Arduino Shield that enables an Arduino board to acquire temperatures from a thermocouple of type K. The shield works with a single supply and takes 5V DC from the Arduino board, the output of the circuit is 0 to 4V DC for 0-degree...

Introduction The voltage signal applied to an op-amp can either be supplied to its non-inverting input (+) or the inverting input (-). These different configurations are simply known as a non-inverting op-amp, and inverting op-amp. In this tutorial, we focus on the non-inverting...

Green energy startup NDB, which is developing a high-power self-charging diamond-based alpha, beta, and neutron voltaic battery that it claims provides up to thousands of years of charge, has announced the completion of two successful Proofs of Concept tests of its nano diamond battery...

I was testing a couple of low-cost laser diodes that come from china and I was wondering why those diodes don’t have any protection/driver circuitry. Those diodes come with a simple series resistor for current control which is not a good idea nor stable. Laser diodes are harmful and...

Introduction This tutorial is an introduction to the Operational Amplifiers, also known as op-amps. The fundamental goal of op-amps is to amplify a voltage difference and it is the reason why we also describe them as differential amplifiers. Op-amps have been invented the exact same...
