Input and Output Each of the 14 digital pins on the Arduino Uno can be used as an input or output, using pinMode (), digitalWrite (), and digitalRead () functions. They operate at 5 volts. Each pin ...

Arduino stands for beginner-friendly and fast development of embedded projects. Playing around with Arduino boards is fun, but not the most efficient way to expand your knowledge. Elektor has ...

Arduino UNO pins -> TX RW wheelbase cable pins Arduino GND -> TWRX Blue wire (2) Arduino pin 12 -> TXRW White wire (3) (data from wheel to base) Arduino pin 10 + pin 2 (SS) -> TXRW Orange wire pin (4) ...

Notes: PCB pin-headers 5V-GND-RST-10-11-12-13 allows to program the ATtiny85 from an Arduino UNO, instead of Arduino Nano. Remove from PCB any pluged Arduino Nano if you are going to program the ...

Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — ...

The Arduino Uno-compatible board has an MCS-51 (often called 8051 instead) instead of the usual ATmega328P/ATmega168. Specifically, [ElectroBoy] uses the AT89S52.

PWM pins work the same way across all Arduino boards, so you don't need to go out of your way to buy a Mega if you already have a board supporting PWM. On the Uno, Nano, and Mini, the PWM pins are ...
