How to Connect Transistors (BJT) and MOSFET with Arduino

Last Updated on March 28, 2022 by Swagatam 12 Comments

BJT PNP NPN pinouts

The interfacing of power devices like BJTs, and MOSFETs with Arduino output is a crucial configuration which allows switching high power loads through low power outputs of an 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 […]

Sequential Timer Circuit using Transistors

Last Updated on March 19, 2019 by Swagatam 23 Comments

sequence2Bgeneartor

In this post I have explained to make a simple sequential timer generator circuit which can be used for getting a sequential triggering of a connected load, or can be simply used like a sequential LED bar graph effect generator, using only transistors. The idea was requested by Mr Babusan.  Technical Specifications Is it possible […]
