This tutorial will guide you through the process of building a tachometer around an Arduino. Tachometers are used to measure rotation rate in Revolutions Per Minute ...

In this experiment we are going to use a element called photoresistor. This sensor allows us to interact with the external environment, through intensity of light. The photoresistor is based on light ...

A keypad is one of the most commonly used input devices in microprocessor applications. In a standard keypad wired as an X-Y switch matrix, normally-open switches connect a row to a column when ...

This repository contains various Arduino projects implemented in C and C++ to explore embedded programming concepts. The goal is to understand low-level hardware interaction, memory management, and ...

Making time for my next small Arduino project, I need to do something with the rotary encoder direction information decoded by this software. A state machine is what I need, but how to implement it?
