I made many audio amplifiers using Class AB configuration. But, working with those big amplifiers are very heavy job. These amplifiers need more power, dual supply and heavy rectifiers/filtering circuits. We cannot power these Class AB amplifiers using single SMPS, A linear power supply with center tapped transformer is must. Now the real problem comes…
Inverters are widely used devices in electronics and electrical circuits. An inverter converts corresponding DC voltage into AC. We are very familiar with linear dc power supplies, which is used to convert 220v Ac into low voltage high ampere DC. In the same way, A high ampere battery or supply is required to step up…
In this post, we will learn how to use Reyax RYS8830 GPS/GNSS Receiver Module to retrieve time and position data from satellite navigation systems. The RYS8830 module from Reyax is based on Sony CXD5605GF/CXD5605AGF technology & comes as a small SMD component. The RYS8830 GNSS modules can be used in tracking devices that need to…
I got my hands on REYAX Lora modules, and in this tutorial, we will configure these modules to communicate with each other. Lora platform is known for its long range as specified by the name LoRa (Long range radio). The normal communication distance is 8Km with rubber ducky antenna. Internet is not required in these…
Hello guys, I made want to make a 7-segment display. But this time with bigger digits and RGB effects. Because this can be used to display some readings like Clock with Nodemcu, temperature monitoring using Arduino. Also, with an option of color changing after each second or next reading. I also have the similar one,…
Well, gaming for some people is the task, we want to do on our smart devices. And today we will do some game test and run some google play store games on raspberry-pi 4. Also, we will know about Android installer and pair our raspberry pi with a big screen to play games. For now,…

Hello guys, today in this basic tutorial we will learn about I2C and I2C addresses. These are generally used in microcontrollers having SDA and SCL pins. As like USB port we can pair up to 127 devices to this I2C port. And like USB this one also need 4 pins, VCC, GND, SDA, SCL. USB…
Hello guys, I am making amplifier circuits and controllers for a long time. But there are some issues with big amplifiers, need high power supplies, big heatsinks, dual channel power and low output. Even we need a big PCB and other combinational modules for controlling bass, treble and subwoofer at all. These become very messy,…
Hello guys, today in this tutorial we have MAX30100 pulse oximeter sensor. We will pair this sensor with our Arduino and check the operation. This will be a simple project and you will get the circuit diagram and code here below. In these types of sketches most of the work is done by libraries itself,…
