These lights are known not only for their dazzling […]
How to Connect LM338 IC in Parallel to Increase Output Current
The LM338 is an adjustable 3-terminal positive voltage regulator capable of providing up to 5 amperes of output current. To increase the output current capability, you can connect multiple LM338 ICs in parallel. When you connect them in parallel, each IC will share the load current, allowing you to achieve higher total current handling capacity. […]
How to Connect Solar Panels in Series and Parallel
In this post we will study how to connect solar panels in series and parallel and also learn how to calculate solar panels in series and parallel. Before I have explained the connection details, it would be important for us to learn some of the important parameters and specifications related to solar panels. Solar Panel […]
How to Connect a Relay through an Opto-Coupler
In the following post I have explained how to drive a relay by using an isolated method, or through an optocoupler device. We will learn three methods, first method is by connecting relay directly with the optocoupler output pins, second method is by using external PNP transistors, and third method is by using external NPN […]
How to Connect Transistors (BJT) and MOSFET with Arduino
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 […]
