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 In this tutorial, you will learn how to create a navigation system by GSM module and Arduino instead of using GPS. At the end What you will learn You will learn more about GSM modules and how to use it with Arduino. You can make a navigation system by GSM. About Navigation In navigation system, a radio station regularly sends signals around. These signals include the exact coordinates of that station. It does n...

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...

Introduction The BIOS, or Basic Input/Output System, is a firmware that controls the boot process and the hardware settings of your computer. Sometimes, you may need to update or repair the BIOS to fix some issues or improve the performance of your computer. However, flashing the BIOS can be risky, as it may cause your computer to become unbootable or unstable if something goes wrong. One of the tools that you can use to flash the BIOS safely and easily is the CH341A programmer, which is a cheap and ve...
