Overview Sometimes in electronic projects, you need to use two or more microcontrollers in your circuit at the same time. Normally, these microcontrollers are connected to each other and keep transmitting data with one another. The transmitting of data between two or more microcontrollers can be done with several communication protocols such as SPI, UART, CAN, USB, etc. Another one which we will be covering here in this tutorial is I2C (Inter-Integrated Circuit) protocol. Using this protocol, one of the mi...

Overview There are two main ways to program the STM32F103C8T6 module, also known as the STM32 Blue Pill: • Serial and USB to TTL converter • ST-Link Tip Sometimes you might find out that the STM32 module you have is not original. And it can’t be programmed through serial. Therefore, we suggest you use ST-Link to program the STM32 Blue Pill. Required Materials Hardware Components STM32F103C8T6 Blue Pill × 1 ST-Link/V2 Programmer × 1 Male to Male Jumper Wire × 1 Software Apps Ar...

Introduction Thermometers and temperature sensors are widely used in many sectors. With advancements in science and technology, different methods and sensors have been developed to measure temperature. These sensors are used in various areas, including industry, homes, labs, and more. Many of these sensors and modules are designed for easy integration with microcontrollers and microprocessor systems. For example, these sensors are designed to work with microcontrollers like Arduino, considering factors such...

Introduction Similar to Arduino IDE, Platform-IO is a programming environment for all types of microcontrollers. It provides an easier programming process and is available as an extension for the VS Code software. One notable advantage of Platform-IO IDE over Arduino IDE is that it automatically selects the appropriate port. In addition, Platform-IO IDE offers code suggestions to help complete and modify your code, and it eliminates errors caused by case sensitivity in Arduino IDE! Some other attractive fea...

Introduction RFID, which stands for radio frequency identification, enables data reading and identification of unique tags using radio waves. RFID modules operate on specific frequencies, requiring tags that match the reader module's frequency. In this article, we will design and implement a simple identification system using a 125KHz RFID module and the Wiegand protocol. Tip While the RFID module used in this article shares similarities in shape and structure with the RDM6300 RFID reader m...

Introduction Are you familiar with single board PCs or mini PCs? They are small computers that even fit in your pocket. Their hardware structure is completely similar to that of ordinary computers. The only difference is that their dimensions have been decreased. One of the first things that any computer needs is an operating system. In this tutorial, we will introduce the best operating systems for Raspberry Pi —one of the most popular mini PCs. This tutorial will help you choose the most suitable oper...

Introduction If you are interested in sensors, you are probably familiar with proximity detection sensors. There are various sensors available for proximity detection; each with its own capabilities and limitations. One method is to use the infrared transceivers. These sensors measure the time it takes for an infrared beam to travel back and forth and calculate the distance between the sensor and the target surface.In this tutorial, we’ll introduce the TMD27713 distance detection sensor. Whether you...
