No multimeter handy (for shame)? Well, as it turns out you can actually measure capacitance using your Arduino Uno, with no external components, and only ~20 lines of code. [Jonathan Nethercott ...

The 16u2 is normally used as the Arduino Uno’s USB interface ... cassette and speaker interface accurate loops to generate and measure frequencies. One of the trade-offs [Damian] accepted ...

Microduino actually isn't the smallest Arduino clone on the market. The Femtoduino, boasting the "same power and pin count of an Arduino Uno," measures just 0.81" × 0.6".

This, however, wasn’t quite good enough for Anthony Garofalo, who instead converted a prototype voltmeter he made using an Arduino Uno and a tiny OLED display into something that displays the ...

Its ability to accurately measure and analyze biosignals can potentially ... and improving healthcare outcomes. The ardEEG Arduino UNO R4 WiFi shield represents a significant leap forward in ...

though we have no plans to discontinue the board,” said Arduino co-founder Massimo Banzi. The Uno R4 provides up to 16 times higher clock speeds, a measure of performance, than the previous ...

Each of the 14 digital pins on the Arduino Uno can be used as an input or output ... each of which provide 10 bits of resolution (i.e. 1024 different values). By default they measure from ground to 5 ...

Here is a useful circuit for Arduino lovers and experimenters. It is a simple digital voltmeter, which can safely measure input dc voltages in 0 to 30V range. The Arduino board can be powered from a ...

The module, developed around the ATmega328P processor, measure 1 x 1.1in and is equipped with a standard ... by the ATmega328P and is said to be 'completely compatible' with Arduino Uno.

If you're on the hunt for the perfect board, then you've probably come across the Uno and Nano. They're two of the most frequently used Arduino variations, but they serve different purposes.
