At the heart of nearly every Arduino project are three core functions: digitalWrite() digitalRead() analogRead() Arduino interacts with the real world by turning pins on and off, reading button states, and measuring sensor values. Even though they seem simple, it’s …

Flash, SRAM, and EEPROM are the three different types of memory that Arduino boards use. Each type has its own job. To write stable, efficient, and scalable sketches, you need to know how these types of memory work and how …
