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...

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...

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...

Introduction If you want to explore the endless features of ESP32 microcontrollers, you’ve come to the right place. All ESP32-based boards come with built-in WiFi and Bluetooth. WiFi allows the ESP32 to connect to the Internet and communicate with other devices, while Bluetooth facilitates wireless communication between the ESP32 and other Bluetooth-enabled devices. In this step-by-step tutorial, we will learn how to configure WiFi on ESP32 using Bluetooth. Whether you’re a beginner or experienced, ...
