Since most of the modern electronics requires more compute power, memory and peripherals set, the popularity of 32-bit microcontrollers is increasing among designers. One of the most commonly used 32-bit devices are the STM32 Microcontrollers from ST Microelectronics which is based on the successful ARM core processors. There are many STM32 Development boards to help you get started but, in this section, we will cover some of the basic STM32 tutorials and sample projects using STM32F103C8 Microcontroller using the popular STM32 Blue Pill Development Board.

Keeping track of extremely low current levels is often essential when developing or testing low-power devices, especially in the field of embedded systems and battery-operated electronics. For battery-related diagnostics or energy-storage testing, the Building a Lithium Cell Capacity Tester tutorial offers a practical method for measuring cell performance over time.…
Indoor and outdoor air pollution significantly impacts human health, causing respiratory issues and reducing life expectancy. Personal air quality monitoring has become essential for protecting ourselves from harmful airborne contaminants like volatile organic compounds (VOCs), particulate matter, and toxic gases. This DIY wearable air quality monitor pendant…
Many of us should be familiar with the popular microcontrollers and development boards like Arduino, Raspberry Pi, ESP8266, NoduMCU, 8051, etc. In fact, for most people, Arduino would have been their first development board, but as we dig deep and begin professional designs, we will soon realize the limitations of Arduino (like cost, versatility, stability, speed, etc.) and…
An oscilloscope is the one instrument every electronics engineer reaches for when a circuit misbehaves. A multimeter tells you a single number, but an oscilloscope shows how a voltage changes over time: the shape of a PWM signal, the bounce of a switch, or the ripple on a sensor output. Bench oscilloscopes are expensive, though, and the best way to understand how one…
DHT11 is a Temperature and humidity sensor which as the name implies is used to measure the atmospheric temperature and humidity in a particular environment or in a confined closed space. The sensor is commonly used in monitoring environmental parameters in many applications like Agriculture, Food Industries, Hospitals, Automobile, Weather Stations etc.

The communication protocols are the integral part of a digital electronics and embedded system. Wherever there is interfacing of multiple microcontroller and peripherals, the communication protocol has to be used in order to exchange bunch of data. There are many types of serial communication protocol available. The RS485 is one of the serial communication protocol and is…
Making wireless projects in embedded electronics becomes very important and helpful as there are no jumbled wires all over which makes the device more handy and portable. There are various wireless technologies such as Bluetooth, WiFi, 433 MHz RF (Radio Frequency) etc. Every technology has its own advantages and disadvantages such as cost, distance or range transfer, speed…
GSM Modules are frequently used in IoT projects since it has the ability to send and receive data remotely. The GSM Modules doesn’t have much dependencies like the Wi-Fi modules. While other wireless modules such Wi-Fi or Zigbee have cons such as short range and cost, the GSM Module have the reliability, long range Since only one SIM card is required with valid plan. Though…
GPS stands for Global Positioning System and used to detect the Latitude and Longitude of any location on the Earth, with exact UTC time (Universal Time Coordinated). This device receives the coordinates from the satellite for each and every second, with time and date. GPS offers great accuracy and also provides other data besides position coordinates.

We all know that the Microcontrollers work only with digital values but in real world we have to deal with analog signals. That’s why ADC (Analog to Digital Converters) is there to convert real world Analog values into Digital form so that microcontrollers can process the signals. But what if we need Analog signals from digital values, so here comes the DAC (…
In this tutorial, we will design a system to read the RFID cards using STM32 and RFID Reader. RFID stands for Radio Frequency Identification which reads information by using radio frequencies. RFID’s are used in many authentication systems like elevator parking system, automated toll collection, maintaining patient information in hospitals, automated data collection etc…
In our previous tutorials, we have learned about SPI and I2C communication between two Arduino boards. In this tutorial we will replace one Arduino board with the Blue Pill board that is STM32F103C8 and will communicate with the Arduino board using SPI bus. In this STM32 SPI Example, we will use Arduino UNO as Slave and STM32F103C8 as Master with Two 16X2 LCD display…
