In a recent blog post on omzlo.com, [Alain] explains how they found a bug in the Arduino SAMD21 analogRead() code which causes the output to be offset by between 25 mV and 57 mV. For a 12-bit ADC ...

The first circuit doubles the resolution of an ADC, in this case, that of the Atmel chip in an Arduino, by converting its output from an integer to a signed integer. It performs this task with a ...

The Arduino Mega's PWM pins are digital output ... they can also be used to generate simulated analog values through a technique called Pulse Width Modulation (PWM). That means these pins can ...

The Arduino board can be powered from a standard 9V battery pack, as usual. As you may well know, Arduino’s analog inputs can be used to measure DC voltage between 0 and 5V (when using the standard 5V ...

The creative adventures with ATtiny series microcontroller are awesome if you know how to play them. ATtinys — especially the ATtiny85s — are all around us, and by using one, we can shrink the size of ...

Nick explains a little more : “The Tsunami is a powerful and flexible signal generator built on the Arduino platform. It’s the best way to get started experimenting with analog signals ...

After all, the Arduino boards come with a host of benefits that make them an excellent choice for a wide array of applications. They feature analog pins for reading analog components (e.g ...

developers and hobbyists looking for a fully featured Arduino Mega compatible PLC may be interested in a new Indiegogo campaign launched today for a new development board featuring 52 analog and ...
