I used the sketch with the random number generator for my test. When I looked at the sketch I immediately saw that the one on the Arduino site had a small error, they neglected to change the name of the variable and used the pone from the potentiometer sketch. The correct sketch is sho...

A bit can be a one or zero, so if the microcontroller unit (MCU) "tosses" this "coin" eight times, it will be able to produce one random byte (eight bits in one byte). I dub this the "Ranalog" method.I then repeat the analogRead experiment with the Arduino Uno R3 and Arduino ...
To generate random numbers on the Arduino we’ll need to use a random number generator. It’s important to understand that random numbers in the computer world are never truly random (some even believe there is no such thing as random numbers in the real world!). Because each time the Ar...

The code was tested on Arduino Nano, Uno and Mega, ethernet chips W5100 and W5500. It may work on other platforms, but: The random number generator (for random MAC) is seeded through watch dog timer interrupt - this will work only on Arduino (credits to https://sites.google.com/site...
Now, you are ready to start experimenting with the Nextion display with Arduino UNO. Wiring Nextion Display to the Arduino Connecting the Nextion display to the Arduino is very straightforward. You just need to make four connections: GND, RX, TX, and +5V. These pins are labeled at the back...
