Ch55xduino is an Arduino-like programming API for the CH55X, a family of low-cost MCS51 USB MCU. The project tries to remove the difficulty of setting up a compiling environment. Users can simply ...

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 ...

Running a program on an Arduino is easy, but have you tried doing it with a Pi? The Raspberry Pi is powerful enough to be a standalone computer and is also good enough to program a microcontroller.

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 ...

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 ...

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 ...
