The Arduino Wire library is a set of communication functions used to read and write data to and from other devices. The library is essential for DIY projects that involve controlling external ...

pinMode' is a built-in Arduino function that sets how a given I/O pin on the Arduino behaves - either input or output. In this case, we're telling the Arduino to use pin LED_BUILTIN (13) as an ...

A n Arduino is a microcontroller — a single board designed to control something and perform a specific task. Unlike a Raspberry Pi, you won't find anything resembling an operating system here ...

When you use the incorrect voltage rating, it can lead to problems with your board and circuit. A voltage lower than the required rating might not be enough to produce 5V and 3.3V at the power pins.

A circuit board for the masses: the Arduino microcontroller. Photo: James Day Check this out,” Massimo Banzi says. The burly, bearded engineer wanders over to inspect a chipmaking robot—a ...

There was a time when building electronics and building software were two distinct activities. These days, almost any significant electronic project will use a CPU somewhere, or — at least &#… ...

Just follow the schematic diagram shown below to complete your own Arduino circuit board! About the ATmega 328 chip It is a good idea to use a socket for the chip. If the chip is pre-programmed, you ...

Yeah, if you are going to use a real Arduino and an LCD shield that is pretty expensive for a frequency counter. I’m not entirely sure what your requirements of reading 3 frequencies are.
