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 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 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: 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 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 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 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 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, 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 Read more…
