[SeanHodgins] has a project in mind where he needs to sample over 500 analog sensors. To get ready, he made a breakout board for 32-channel analog multiplexer device he wants to use. He put the pro… ...

This library is used in order to abstract away a few of the details to do with analog multiplexing and demultiplexing. It assumes the following: The multiplexer is analog and is compatible with the ...

There are two ways to go about lighting an RGB LED module on any Arduino board. The usual method is to use the Arduino’s analog pins to send PWM signals to the module. This lets you mix each color, ...

While a Raspberry Pi is a full-fledged computer that can do more complex things than an Arduino microcontroller, it's not the best choice for every project.

The built-in function analogRead() can be used to read any of the analog pins on the Arduino. However, that method blocks while waiting for the Analog-to-Digital Converter (ADC) to read the analog ...

The analog voltage for the meter can be generated by PWM. The Arduino PWM outputs have a frequency of about 500Hz which means that the pin cycles from 0 to 5V and back to 0 again 500 times a second.

V-USB (Virtual USB) is especially useful for those of us who build standalone Arduino projects with the ATMEGA328. Unlike the Arduino Leonardo and its ATMEGA32U4, the ATMEGA328 does not have a ...

Options to power the Arduino Nano include USB, VIN, and 5 volt pin, meaning you have power options for almost any situation.
