An early Arduino board [28] with an RS-232 serial interface (upper left) and an Atmel ATmega8 microcontroller chip (black, lower right); the 14 digital I/O pins are at the top, the 6 analog input pins at the lower right, and the power connector at the lower left.
The word "uno" means "one" in Italian and was chosen to mark a major redesign of the Arduino hardware and software. [7] The Uno board was the successor of the Duemilanove release and was the 9th version in a series of USB-based Arduino boards. [8] Version 1.0 of the Arduino IDE for the Arduino Uno board has now evolved to newer releases. [4]

The Arduino Nano is an open-source breadboard-friendly microcontroller board ... Analog input pins: 8; DC per I/O ... (i.e. anything besides an upload of new code ...
The principle is to adjust the DAC's input code until the DAC's output comes within ± 1 ⁄ 2 LSB to the analog input which is to be converted to binary digital form. Servo tracking ADC: It is an improved version of a counting ADC. The circuit consists of an up-down counter with the comparator controlling the direction of the count.
The Makey Makey board [10] was originally designed around the Atmel 32U4 microcontroller. [11] The controller uses all 12 analog input pins on the 32U4 microcontroller in combination with a pull-up resistor array to sense the low voltages returning from conducting materials like fruit or skin.
Special input/output (Special I/O or SIO) are inputs and/or outputs of a microcontroller designated to perform specialized functions or have specialized features. Specialized functions can include: Hardware interrupts, analog input or output; PWM output; Serial communication, such as UART, USART, [1] [2] SPI bus, or SerDes. External reset ...
