Arduino programming has multiple functions to read and manipulate data using serial communication. Using these functions, we can design different Arduino projects and create a real time solution. One common task when working with microcontrollers is to convert decimal numbers to hexadecimal format. In ...
11 if I remember, where your setup calls for pin 3. Once that change is made in the code, it captures the IR perfectly and then goes on to control the LEDs perfectly. I'm well on my way to my
Wire.write(decToBcd(hour)); Wire.write(decToBcd(dayOfWeek)); Wire.write(decToBcd(dayOfMonth)); Wire.write(decToBcd(month)); Wire.write(decToBcd(year)); Wire.write(00010000); // sends 0x10 (hex) 00010000 (binary) to control register - turns on square wave Wire.endTransmission(); ...

To fix this, use a logic shifter chip that converts between 3.3V and 5V logic. This library has been successfully tested on many boards including: ESP32; STM32; Mega 2560; DUE; ATmega328 and Atmega32u4 based boards; ATtiny85, Raspberry Pi Pico (RP2040) and more. See Boards where this...
Minimizing String Memory, below, shows you how to avoid creating short lived temporary Strings most of the time. However some times they are unavoidable. Examples are adding floating point numbers or adding integers in hex format and using the substring function which creates and returns a String...

Boards including the Uno, Duemilanove, Diecimila, Nano, and Mega have a chip to convert the hardware serial port on the Arduino chip to Universal Serial Bus (USB)for connection to the hardware serial port. Other boards, such as the Mini, Pro, Pro Mini, Boarduino, Sanguino, and Modern Dev...

Connect the IR receiver accordingly to the schematics below. Code To control the IR receiver, you need to install theIRremote Libraryin the Arduino IDE. Installing the IRremote library Go toSketch>Include Library>Manage Libraries. The Library Manager should open at the left sidebar of the IDE. ...
