In this post we are talking about this handy little gadget called a 5V single-channel relay module. It is super useful for our microcontroller projects whether we are using Arduino, Raspberry Pi, or even the ESP8266/ESP32. Let us break it down together, what it is, how it works, and how we can connect it. Understanding […]

DC-DC Boost Module (0.9V~5V) to 5V 600mA USB Step-up Board
So this is a DC-DC boost converter that takes a low voltage (0.9V to 5V) and steps it up to a stable 5V. We use this when we have a small battery, but we need 5V output, like for USB devices. It is super useful for battery-powered projects and small electronics. Main Features How It […]
Reed Switch Sensor Module Explained with Circuit Diagram
Here we will try to understand this reed switch sensor module which may look small and nothing much, but it is actually very useful thing when we want to detect a magnetic field or just want to know if a magnet is coming closer or going away. This thing is called a reed switch sensor […]
Impact Collision Switch Sensor Module and Circuit Diagram
Here we are going to learn about a very interesting small sensor called the Impact Collision Switch Sensor Module. This module is super simple but very useful especially when we want to detect a shock, collision, hit or a sudden tap on a surface. Now let us go step-by-step to understand everything about it. What […]
Programmable 35238-MP Timer Module? How to Use it
So this 35238-MP Multi-Function Timer module is an digital adjustable programmable timer which we can use it for doing time-based automation things. Inside it, there is a microprocessor that watches time very closely and makes the relay turn ON or OFF after a set time. So this thing is good when we want to turn […]
Universal H-Bridge Circuit Module
In this article I will elucidate a simple universal H-bridge module using BJTs and N-channel MOSFETs. This module can be integrated with any standard oscillator ICs such as IC 4047 or IC SG3525 or even IC 555, to create a highly efficient H-bridge inverter circuits. Why using 4 N-channel MOSFET H-Bridge is the Most Efficient […]
