Here’s a great way to use and adapt a world of projects and example code – the Adafruit METRO. It’s a derivative of the Arduino UNO board (RS 769-7409) and it runs so the ATmega328P at 16 MHz with 32 KB of flash and 2 KB of RAM. So it’s just the thing for those simple projects. Featuring 19 GPIO pins including analogue inputs, hardware UART, SPI and IÂ²C, timers and PWM, the METRO’s logic level is 5 V (though you’ll find it easy enough to convert this to 3.3 V).
