In this post we will be talking about this MAX4466 microphone amplifier module, right? So this is a tiny little circuit that can amplify weak sound signals from an electret condenser microphone (ECM). That means it is going to take a very small electrical signal from the microphone and then boost it up so we […]

How to Connect 5V Single Channel Relay Module
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 […]
Arduino Digital Clock Using RTC Module
In this post I will show how to construct a digital clock using RTC or Real Time Clock module. We will understand what “RTC” module is, how to interface with Arduino and what it does. By: RTC module is a circuit, which keeps track of current time accurately. It does two functions, it communicates with […]
Easy H-Bridge MOSFET Driver Module for Inverters and Motors
If you are wondering if there’s an easy way to implement an H-bridge driver circuit without using the complex bootstrapping stage, the following idea will precisely solve your query. In this article I have explained how to build an universal full-bridge or H-bridge MOSFET driver circuit, using P-channel and N-channel MOSFETs, which can be used […]
How to Use TTP223 Capacitive Touch Switch Module [Pinouts Explained]
In this article I have explained how to connect and use the TTP223 capacitive touch switch module. These modules work using 2.5V to 5V. They are all pre-debounced, all you need is to provide the DC supply across the VC and GND terminals, and you get an output in the middle. So it is really […]
