One of the most misunderstood parts of Arduino projects is EEPROM (Electrically Erasable Programmable Read-Only Memory). Beginners often either ignore it or use it wrong by writing too often, which wears out the memory too soon. EEPROM is not a …

As Arduino projects grow beyond simple sketches, code based on delay() statements and deeply nested if conditions quickly becomes hard to read, hard to debug, and unreliable. This is where state machines become essential. A state machine is a programming …

Introduction Matter is a new standard for smart homes that aims to fix one of the biggest problems with connected devices: they don’t always work with each other. Smart home ecosystems have been broken up for a long time, with …

Arduino compilation errors usually fall into a few predictable buckets: Syntax errors: missing semicolons, braces, quotes Name/Scope errors: variables/functions not declared, wrong casing Type errors: mixing incompatible types, wrong function signatures Library errors: missing libraries, wrong versions, wrong include names …

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 …

The Arduino Serial Plotter is a built-in tool in the Arduino IDE that allows you to visualize live data from your Arduino board in real time. This is particularly useful when working with sensors, analog readings, or debugging data. Unlike …

In this article we look at a Triple-axis Magnetometer, the MMC5603 and connect it to an Arduino Uno Sensor Information This sensor can sense ranges from ±30 Gauss (±3000uT or ±3mT) with no range-setting required and full 20 bit output …

In this article we look at an Ambient Light sensor, the LTR-329 and connect it to an Arduino Uno Sensor Information The LTR-329 provides 16-bit light measurements for both Infrared and Visible+IR spectrums. Subtract one from the other to get …
