Arduino has shrunk the UNO R4 with the Arduino Nano R4 board equipped with the same 48 MHz Renesas RA4M1 32-bit Arm ...

If your Arduino runs out of I/O lines, you can always add one of the several I/O expander chips that takes a serial interface to set its several pins. Or perhaps you could buy something like an Ard… ...

Take note: Arduino has its own set default values of modulation frequency for its PWM pins. For pins 3, 9, 10, and 11, it is approximately 488 Hz, and for pins 5 and 6, it is about 977 Hz. Though ...

Most projects are built on abstractions. After all, few of us can create our own wire, our own transistors, or our own integrated circuits. A few months ago, [Julian Ilett] found a problem using th… ...

That's because the Arduino Nano 3.0 is intended for breadboarding, where the compact dimensions will leave more space for other components. There are 14 digital I/O pins – six of which provide ...

Another pin you can use on the Nano to power it up is the 5V pin (located on Pin 27, close to the VIN pin at the end of the board). This pin mostly serves as a power output pin that supplies power ...

While the pinout is very similar to the Arduino Nano’s, there are four (12-bit) analogue inputs rather than eight (10-bit). Some digital GPIO pins are numbered differently too.
