Input and Output Each of the 14 digital pins on the Arduino Uno can be used as an input or output, using pinMode (), digitalWrite (), and digitalRead () functions. They operate at 5 volts. Each pin ...

PWM pins work the same way across all Arduino boards, so you don't need to go out of your way to buy a Mega if you already have a board supporting PWM. On the Uno, Nano, and Mini, the PWM pins are ...

Arduino also upgraded the R4 WiFi's analog-to-digital converter (ADC), which is responsible for reading data from the analog inputs. On the Rev3, the ADC supports up to 10-bit resolution, with ...

The Uno board has 14 digital input/output pins – with six that can be used as PWM outputs – and six analogue inputs. Other features include a 16MHz ceramic resonator, USB connection, an ICSP header, ...

The Type K thermocouple is the most common type. It’s inexpensive, accurate and reliable and has a wide temperature range. This article shows how to use an Arduino Uno/Nano microcontroller with an ...

The Arduino UNO R4 boasts a 3x performance increase over the UNO R3 and , in addition, SRAM has been upgraded from 2kB to 32kB, and flash memory from 32kB to 256kB to support more complex projects.
