Sine wave generation using dsPIC is one of the most popular topics in electronics. Many engineers and hobbyists try this project. So in this article, I’ll start writing on sine wave generating using dsPIC. About dsPIC: The dsPIC (digital signal controller) is a microcontroller family developed by Microchip Technology. They Read more
Sometimes, we need to measure or check the internal temperature of the microcontrollers for safety reasons. So, in this article, I’ll cover how to measure the Internal Temperature of STM32 microcontrollers using the STM32CubeIDE compiler. So let’s begin. Why need to measure Internal Temperature? The answer is simple, for safety. Read more
R503 is a popular capacitive fingerprint sensor. We can use this sensor for industrial purposes. In this article, we’ll make a fingerprint attendance system with R503 capacitive sensor with Arduino. I hope this project will help many people make their own attendance system. So, let’s start! About R503 Capacitive fingerprint Read more
In this article, we are learning about PWM Generation with STM32. Here we are using STM32F103C8Tx MCU, but you can also follow the same way for most of the other MCUs. So let’s start! What is a PWM signal: PWM or Pulse Width Modulation is a kind of digital signal Read more
DMA is an important feature of any microcontroller. In this article, we are going to learn how we can use DMA for ADC reading with STM32. Here I’ll continue from the previous article. So let’s start. About the previous article: In our previous article, we discussed how we can use Read more
In this article, we will learn ADC Reading with STM32 BluePill or other STM32 ICs. We are using CubeMx IDE and here is how we can configure the code for this purpose. Why do you need ADC? ADC is one of the fundamental features of microcontrollers. ADC helps read analog Read more
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
