There are two kinds of input and output pins on an Arduino: digital and an analog. Let's have a look at them going forwards. Digital pins . Digital pins are useful for reading the state of devices like buttons and switches or controlling things like relays and transistors or LEDs. These examples have one thing in common: they only have two possible states. A button can be either pressed on. Essentially your Arduino will read a value between 0 and 1023 on the analog pin and will need to compare this value to a particular range in order to identify which button has been pressed. We use a range rather than an absolute value because the analog input and resistors are very sensitive to external influences such as temperature.

The Arduino's digital pins read only two states : when there is voltage on an input pin and when there is not. This kind of input is usually called digital ( or sometimes binary for two state). These states are commonly referred to as HIGH and LOW. HIGH is the same as saying there is voltage here!' and LOW means there is no voltage on this pin! When you turn an OUTPUT pin HIGH. Whenever one of the directional buttons is pressed, Arduino will move the mouse, mapping a HIGH input to a range of 5 in the appropriate direction. The fifth button is for controlling a left-click from the mouse. When the button is released, the computer will recognize the event. Components Required. You will need the following components

  1. An Arduino library to capture button presses on multiple buttons through a single analog pin. AnalogPin: Arduino Library for AnalogPin: AnalogTouch: AnalogTouch library for Arduino: Anyleaf: Driver for the AnyLeaf pH, EC, and RTD sensors. ArduMax AD5241 Driver: Driver for Analog Devices AD5241/2 and AD5280/2 digital potentiometers. ArduMax MCP41xxx Driver: Driver for Microchip MCP41xxx/42xxx.
  2. Daten-Pin des I2C-Bus ist bei den meisten Arduinos mit dem analogen Pin 4, also A4 zu verbinden. SCL: Clock-Pin des I2C-Bus ist (meist) mit A5 zu verbinden. SQW: benötigen wir nicht. Der Pin kann verwendet werden um ein Rechtecksignal auszugeben. Der Chip liefert immer 7 Byte an Information über den I2C-Bus, nämlich Datum und Uhrzeit - allerdings BCD-codiert. BCD bedeutet dabei binär.
  3. analogRead(pinNumber) - analogRead() reads from one of the Arduino's analog pins and outputs a value between 0 (voltage at the pin = 0V) and 1023 (voltage at the pin = 5V), if the analog pin voltage was 2.5V, then it would print: 2.5/5*1023 = 512 analogRead() takes one argument - the name of the analog pin (A0-A5) to read from
  4. The Pro Micro's I/O pins -- 18 in all -- are multi-talented. Every pin can be used as a digital input or output, for blinking LEDs or reading button presses. These pins are referenced in the Arduino IDE via an integer value between 0 and 21. (The A0-A3 pins can be referenced digitally using either their analog or digital pin number)
  5. Following figure shows the placement of analog pins on the Arduino Uno Board. If you have already got a hold of some features of Arduino Board, you must have known that analog pins are 10-bit pins. It means each pin can store 0 - 1023 values. Analog pins are different than digital pins as the later can store only two values: HIGH and LOW while the former comes with an ability to store any.
