As explained by Arduino to Go, each color band on the resistor corresponds to a number but this can differ depending on the band's placement. It's not complicated, but the sheer number of colors ...

AnalogPin is an Arduino class that adds noise filtering and smoothing to analogRead(). Furthermore it can speed up the analogRead() function by tuning the pre-scaler. This latter is AVR only.

An Arduino can measure time, a coil and a resistor will create a delay proportional to the circuit values, and metal around the coil will change the coil’s inductance.

Yes, in less than 1/4 of one second an Arduino can open any of the millions of these locks in service. The exploit in Onity programmable keycard locks was revealed by [Cody Brocious] at the ...

This example demonstrates how to use an analog sensor with an Arduino. The analog sensor used is an LDR (Light Dependent Resistor) that measures the light intensity. Based on the detected light level, ...

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 ...

When working with Arduino boards for the first time, you're bound to make some mistakes, but these are some of the most common pitfalls you can avoid.
