Arduino Core for ESP32 has received a wrapper library that makes it easier to use ESP32-H2 and ESP32-C6's Zigbee radio in Arduino projects.

Some of the first steps toward working with Arduino is understanding how to write code for it. The good news is that it's made with beginners in mind.

In an era where homeowners frequently leave for work or education, robust security for residences is imperative. Traditional security measures, including window and door locks, present challenges such ...

KeypadInt lib uses a buffer of up to 10 keys that are stored in case the CPU is occupied in other tasks. KeypadInt example is based on example of Keypad.zip library (from Mark Stanley and Alexander ...

The top ten Arduino library authors *Glad to hear that, despite postmodern theory, the author is not dead. The library isn't dead either, which would please Umberto Eco ...

The library files provide useful functions to make it easy to communicate with matrix keypads (like a 4x4 keypad) that use the I2C communication protocol. The demo program shows the usage of the ...

Next is a project example, where the Arduino is instructed to do something based on a correct key (secret number) being entered into the keypad, probably the most demanded application of the keypad.

[Andrea] just sent us this great student hack he made for his room. He’s constructed an Arduino keypad door lock — without using any proper fastening hardware! The entire build is made … ...
