    However, there is room for confusion. The PIC data sheets show an inverted socket and do not provide a pictorial view of pinouts so it is unclear what side of the socket Pin 1 is located on. The illustration provided here is untested but uses the phone industry standard pinout (the RJ11 plug/socket was original developed for wired desktop phones).

    en.wikipedia.org/wiki/Atmel_AVR_instruction_set

    The Atmel AVR instruction set is the machine language for the Atmel AVR, a modified Harvard architecture 8-bit RISC single chip microcontroller which was developed by Atmel in 1996. The AVR was one of the first microcontroller families to use on-chip flash memory for program storage.

    Among the first of the AVR line was the AT90S8515, which in a 40-pin DIP package has the same pinout as an 8051 microcontroller, including the external multiplexed address and data bus. The polarity of the RESET line was opposite (8051's having an active-high RESET, while the AVR has an active-low RESET ), but other than that the pinout was ...

    en.wikipedia.org/wiki/ATtiny_microcontroller...

    ATtiny (also known as TinyAVR) is a subfamily of the popular 8-bit AVR microcontrollers, which typically has fewer features, fewer I/O pins, and less memory than other AVR series chips. The first members of this family were released in 1999 by Atmel (later acquired by Microchip Technology in 2016).

  6. ATmega328 - Wikipedia

    en.wikipedia.org/wiki/ATmega328

    ATmega328 is commonly used in many projects and autonomous systems where a simple, low-powered, low-cost micro-controller is needed. Perhaps the most common implementation of this chip is on the popular Arduino development platform, namely the Arduino Uno, Arduino Pro Mini [4] and Arduino Nano models.

    is the resistive power loss (SI unit: watt) The motor constant is winding independent (as long as the same conductive material is used for wires); e.g., winding a motor with 6 turns with 2 parallel wires instead of 12 turns single wire will double the velocity constant, , but remains unchanged.

    Versalino Uno 1.1 Compact board with pins in two similar layouts "Bus A" and "Bus B". 6 volt input 3.5 mm plug power. Programmed with FTDI. LeoStick [216] Freetronics ATmega32U4 Compact version of the Arduino Leonardo (which can be plugged straight into a USB port without a cable) and has a buzzer and a 3-in-1 RGB LED. Wattuino Nanite [217] [218]

    Some common pinouts [20] for 2.54 mm (0.100 in) pin headers are: ARM 2×10 pin (or sometimes the older 2×7), used by almost all ARM-based systems; MIPS EJTAG (2×7 pin) used for MIPS based systems; 2×5 pin Altera ByteBlaster-compatible JTAG extended by multiple vendors; 2×5 pin AVR extends Altera JTAG with SRST (and in some cases TRST and an ...
