With all the materials needed in hand, it is time to get on with the build. The first thing to do is print out the 3D part you’ll need for this build. We have included the models above, but you can ...

Unfortunately, when I uploaded the code to my Arduino R4 WiFi, its performance did not meet expectations.The LED did not blink at a two-second interval and it was unable to print the complete message ...

Why BMP280, you ask? Because this sensor costs low and it only provides both temperature and barometer readings, and as pressure changes with altitude, we can also use it as an altimeter with ±1 meter ...

Arduino RFID technology works by using electromagnetic waves in the radio frequency spectrum for wireless communication and data transfer between RFID tags and readers. From supermarket anti-theft ...

Infrared line tracker modules hardly need an in-depth explanation as they’re very familiar to most electronics and robotics hobbyists. In this post I’ll discuss a popular and cheap infrared line ...

This is a library allowing sending and receiving SMS messages in asynchronous way. Is has its limitations but proved to be faster than when using fixed delays and allows your application to do ...

I was having a chat recently with someone, and it surprised me that she had an amateur radio license. I suppose it shouldn’t have come as much of a surprise; after all, getting a ham radio license is ...

Last week I spent most of my leisure time studying nonvolatile memory chips. The result was a better understanding of Arduino’s EEPROM. This might look like novice work, but I hope my thoughts will ...

Creating a new sketch in the Arduino IDE makes the editor open a template containing skeletons for the functions setup and loop. What if you don't like this template? Can you edit it somehow? Yes, you ...
