UP DOWN Logic Sequence Controller Circuit

Using a set of latch/reset networks it becomes possible to allow a logic to move in a forward sequence, switching ON a given set of outputs HIGH, in response to an alternating input clock. And once the max limit is reached, the input clocks begin shutting down or withdrawing the sequence in the opposite order. … Read moreUP DOWN Logic Sequence Controller Circuit

How to Connect Transistors (BJT) and Mosfet with Arduino

In this article we elaborately discuss the correct methods of using or connecting transistors like BJTs and mosfets with any microcontroller or an Arduino. Such stages are also referred to as “Level Shifter” because this stage changes the voltage level from a lower point to a higher point for the relevant output parameter. For example … Read moreHow to Connect Transistors (BJT) and Mosfet with Arduino

Understanding Amplifier Circuits

In general, an amplifier can be defined as a circuit designed to boost an applied low power input signal into a high power output signal, as per the specified rating of the components. Although, the basic function remains the same, amplifiers could be classified into different categories depending on their design and configurations. Circuits for … Read moreUnderstanding Amplifier Circuits

Learning Basics of Semiconductors

In this post we comprehensively learn regarding the fundamental working principles of semiconductor devices, and how the internal structure of semiconductors function under the influence of electricity. The resistivity value between these semiconductor materials neither has a complete conductor characteristic nor a complete insulator, it is in between these two limits. This feature may define … Read moreLearning Basics of Semiconductors
