An Arduino Uno has 14 digital input/output (I/O) pins1. Conventional, i.e., not PWM, operation of the digital I/O pins is controlled with the pinMode, digitalRead and digitalWrite functions. The pinMode function is used to congure a pin as an input or output. Exercise 3 - a RESTful Arduino web application. The Arduino sketch for the exercise. We also provide you with a PDF file that has color images of the screenshots/diagrams used in this book. It is highly recommended that you visit the official Python tutorials at https The Arduino Mega 2560 is a microcontroller board based on the ATmega2560 (datasheet). It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header
