I am receiving a MQTT message which contains a payload that I want to read into an integer. This integer would be the number of minutes my alarm would ring (I trigger a relay),

Converting Between Data Types in Arduino

The standard library has std::bitset for this purpose.. This is included out of the box for ARM and Espressif boards, just #include.. You can use this port if you’re using an AVR:

Understanding how to convert between types ensures your Arduino program works smoothly. Common Data Types in Arduino. Before we dive into conversions, here’s a

I use Wire.h library but I can only send „byte“ or „char“ ( with Wire.send() ) Thanks to nice example I succed to send byte or char (So my wiring between both arduino is correct)

I am using a library the return a „byte HEX“ value via I2C from a DS3231 real time clock chip then I am storing the value in an „int registerValue“ but the value is in HEX. When I

Is there any way that I can take the buffer string and take each number separated by comma out individually? One simple idea when capturing from the serial port:
