Design a Voltage Controlled Current Source Circuit using Op Amp

Design a Voltage Controlled Current Source Circuit using Op-Amp

In a voltage-controlled current source circuit, as the name implies, a small amount of voltage across the input will proportionally control the current flow across the output loads. This type of circuit is commonly used in electronics to drive current-controlled devices like BJT, SCR, etc. We know that in a BJT the current flowing through the base of […]

Current Divider Circuits Explained with Formula and Practical Hardware

When designing an electronic circuit, there are lots of situations when a circuit requires different values of voltage and current sources. For example, when setting the preset voltage for an Op-Amp, it is very common to use a potential divider circuit to obtain the required voltage values. But what if we need a specific value of current?

Simple GPIO Functions on Nuvoton N76E003 LED Blinking and Controlling LED using a Push Button

Simple GPIO Functions on Nuvoton N76E003 – LED Blinking and Controlling LED using a Push Button

In our previous tutorial, we used a basic LED blinking program as a getting started with N76E003 guide, we already learned how to configure the Keil IDE and set up the environment for programming the nuvoton microcontroller unit N76E003. It is the time to move a little bit further and use the basic GPIO interface for controlling additional hardware. If you
