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

Two new variants of the Arduino Uno development board, the lightweight Uno R4 Minima and the full-fledged Uno R4 WiFi, are each powered by a 32-bit microcontroller. These next-generation Uno boards ...

Arduino has announced the new UNO R4 board family for prototyping and learning. The new models feature a faster microcontroller, a USB-C connector, improved power, Wi-Fi and Bluetooth LE, and more.

PWM controls the the brightness of each of the LEDs. Roughly, every 1/500th of a second, the PWM output will produce a pulse. The length of the pulse is controlled by the analogWrite function.

The Metro board is also equipped with 19 GPIO pins, 6 of which are Analog and 2 of which are reserved for the USB-serial converter. There’s also 6 PWMs available on 3 timers offering 1 x 16-bit ...
