Those who worked with Arduino and built any GPRS or IoT project, are familiar with Adafruit_FONA Library. This library is handy for the Arduino platform to build any GSM, GPRS, or related project. But unfortunately, this library doesn’t work with ESP32 directly. And I had awful experiences with this issue. Read more
In some cases, Logging Data to Excel from Arduino become necessary for data analysis especially when a graphical analysis of multiple data is necessary. At the same time, we can use Arduino or any kind of device that is sending data to a PC, we can log them. Let’s see Read more
When you are working with battery depending low power-consuming circuits, then you may need this innovative power switch. The concept is to save energy while the device is not operating but the battery is connected. Why we need to save energy: We use electricity almost all the time. In some Read more
In this article, we will learn how to detect USB ports or devices in Pi automatically. So, you do not need to search from the command box. This simple line of code helps a lot while working on projects. Anyway, let’s start. Manual way: There is a manual way to Read more
In this article, we are going to learn how you can use a GSM module with your Raspberry Pi to send SMS or do whatever you need to do. Here, we’ll use a GSMHat for raspberry pi which will be connected through USB with the Pi. So let’s start! GSM/GPRS/GNSS Read more
This is a complete practical guide on how you can Connect to Raspberry Pi from your Laptop/Desktop using VNC viewer. This guide is fully informative and completely based on practical steps. Also, this is very important and you should not miss any points. So read every step carefully. First thing Read more
DC motor is very common and we use it for different purposes. But problem is, when used with a sensitive circuit, this DC motor creates problems in the working of the circuits. Such as communication disturbed, signal distortion, noise in amplifiers, and so on. In this article, we are going Read more
In this article, we are going to see how we can store String in the EEPROM of a microcontroller and recall those strings to print on display or use it for different purposes. Usually, we use ROM as the main memory and RAM for variables. But this technique will save Read more
This is a mini article where you are going to learn about an One Button push on push off switch circuit. Sometimes we need a small button switch that can be used as one push switch on, another push switch off. As this is a logical operation, something digital circuit Read more
In this article, we are going to learn about Interfacing External EEPROM with a PIC microcontroller. All the microcontrollers do not have EEPROM but sometimes, we need to save some information in EEPROM while the MCU does not have any. In that case, external EEPROM is the only solution. So Read more
