Raspberry Pi Raspberry Pi is a mini computer based on an ARM processor. Since many different operating systems can be installed on this mini-computer, it can be used in various robotics, programming, and electronics projects. There are different types and versions of this mini-computer. The newest versions are Raspberry Pi 3 Model A+ and Raspberry Pi 3 Model B+. More than 19 million Raspberry Pi boards have been sold around the world until now. Raspberry Pi 3 Version B+ Specification:...

HN3808-AB Rotary Encoders Features A photoelectric rotary encoder is an electromechanical device that has an internal shaft inside a cylindrical space that looks like an motor. The circular plate inside it has two slits. An optical transmitter sensor is located on one side and an optical receiver sensor is located on the other side. When a gap is placed between the two sensors, the sensors and finally the receiver are connected to the microcontroller. Rotary encoder is commonly used to determine the positio...

Overview Have you ever wanted to use 2 sensors with the same I2C address at the same time, not knowing what to do? Faced some serious challenges in doing that? In a lot of projects, we have used different modules and sensors that support I2C communication protocol. Sometimes, we have interfaced some I2C modules with a microcontroller in our projects. If they all have different I2C addresses, we could easily interface them, facing no serious trouble. But, if 2 or more of the modules had the same I2C address...

Are you looking to burn a bootloader and program AVR microcontrollers easily and efficiently? In this tutorial, we will guide you through the process using an Arduino Uno board and the Arduino IDE software. By utilizing the In-circuit Serial Programmer (ISP) feature of an Arduino Board, you can quickly install the bootloader and program various AVR microcontrollers. Overview There has definitely been times that:Your microcontroller IC has been burntOr you have obtained a new microcontroller and are...

A thermocouple module is a package that contains a K-type thermocouple and a display. It can measure and display high temperatures up to 800°C. What is a Thermocouple? A Thermocouple is a well-known electrical component for measuring temperature. This component also has two dissimilar electrical conductors that form an electrical junction. The voltage produced by the thermocouple is highly dependent on the temperature of the thermocouple. Using this voltage, we can m...

XY-TR01 Digital Temperature & Humidity Control Module The XY-TR01 Digital Temperature and Humidity Thermostat Module is great for controlling humidity and temperature. It has a digital sensor called SHT20. In addition, its user interface comes with a digital display to show data and four control buttons to adjust humidity and temperature. The module also has two separate relays (maximum current: 10A) to independently control the cooling/heating and humidification/dehumidification m...

Introduction Have you ever had difficulties while uploading code to an ESP32 board? This article deals with one of the most common errors that occurs during code uploading: “Failed to connect to ESP32: Timed out waiting for packet header.” To tackle this problem, we will introduce two methods. Steps to Troubleshooting “Failed to connect to ESP32” Error First of all, disconnect all wires connected to the ESP32 board. This simple thing might solve the issue! (Because the serial or USB pins could be in...

Introduction Analog-to-digital converters (ADCs) convert analog data into digital format. The 16-bit ADS1110 module offers good accuracy for measuring analog data with the microcontroller. In this tutorial, we will interface an ADS1110 module with Arduino. The communication between the module and the Arduino board is done by the I2C protocol. Tip: The built-in 10-bit ADC of Arduino has a lower accuracy compared to the ADS1110 module. Therefore, to measure the anal...
