Many times like a multimeter, I expected to have a handy serial terminal nearby such that I will connect those two wires [Tx, Rx] of the probe and will be able to see whether the sensor is really ...

We’ve already covered inexpensive offline voice recognition modules based on US516P6 or TW-ASR ONE microcontrollers that allow people to add smarts to their projects without a network connection for ...

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 ...

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 ...

This is a useful addition to my previous article “Arduino EEPROM”. The article is still available. I have provided a link here for convenience https://www.edn.com ...

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 ...

The Arduino Serial Data Exporter library was created in order to streamline data exported via USB serial. Manually printing via Serial.print() and Serial.println() can quickly bloat code, particularly ...

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 ...

In our previous tutorial learned about SPI communication in Arduino. Today we will learn about another Serial Communication Protocol: I2C (Inter Integrated Circuits). Comparing I2C with SPI, I2C has ...
