The Arduino Uno is a microcontroller board based on the ATmega328. It has 20 digital input/output pins (of which 6 can be used as PWM outputs and 6 can be used as analog inputs), a 16 MHz resonator, a ...

For such cases we use serial to parallel converter chips or shift register. A shift register chip takes data from UNO board serially and gives output in 8 bit parallel configuration. Components ...

Published in the October 2013 Edition PLEASE NOTE:- In some editions fo the Magazine (GB, DE), the Temprature sensor is listed as a DS1820 - This should read DS18 B 20. The DS1820 is an old part and ...

The heart of the clock is the Arduino Uno, a versatile microcontroller known for its ease of use and flexibility. The Arduino Uno reads the time from a DS1302 real-time clock (RTC) module.

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 ...

Arduino UNO R4 RA4M1 HOCO to External-Clock on EXTAL pin change setup code. With 10.00MHz external input; over-clocking to 80MHz, and under-clocking down to 5MHz. This is an update to the previous ...
