If you need to control more than one chip at once, create multiple instances (objects) of the PT2258 class like this (example with two chips): PT2258 mixerA(0x84); // CODE1 = 0, CODE2 = 1 (for example ...

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 ...

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 ...

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 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 ...

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 ...
