Arduino Store Array Into EEPROM

In this tutorial I’ll show you how to store an array into the Arduino EEPROM. First we’ll look at arrays composed of int numbers (2 bytes each), and then we’ll do the same with long numbers (4 bytes each). I strongly advise you to check how to store an int number into EEPROM before reading … Read more

Arduino Fast digitalWrite

So, you’re using the digitalWrite() function in most of your Arduino projects. But you may come to a point when this function is too slow, because you have to use it a lot, and with a high frequency. In this tutorial I’ll show you how to make a fast digitalWrite(), so you can speed up … Read more
