<\/figure><\/div>\n\n\nUpdated 17 December 2024<\/em><\/p>\n\n\n\n This project is divided into two parts:<\/p>\n\n\n\n To follow this project you need the following parts:<\/p>\n\n\n You can use the preceding links or go directly to MakerAdvisor.com\/tools<\/a> to find all the parts for your projects at the best price!<\/p> The infrared receiver is the component shown in the figure below. This is the TSOP4838.<\/p>\n\n\n Infrared receiver pins:<\/strong><\/p>\n\n\n\n When you press your remote control, it sends infrared modulated signals. These signals contain information that your receiver collects.<\/p>\n\n\n Each button sends specific information. So, we can assign that information to a specific button.<\/p>\n\n\n\n In this part of the project you need to decode the IR signals associated with each button.<\/p>\n\n\n\n Connect the IR receiver accordingly to the schematics below.<\/p>\n\n\n To control the IR receiver, you need to install the IRremote Library<\/a><\/strong> in the Arduino IDE.<\/p>\n\n\n\n Copy the following code to your Arduino IDE, and upload it to your Arduino board. Make sure that you have the right board and COM port selected.<\/p>\n\n\n View raw code<\/a><\/p>\n\n\n\n Open the serial monitor at a baud rate of 9600.<\/p>\n\n\n In this project you want to control 3 LEDs. Choose 6 keys on the remote control for the following tasks:<\/p>\n\n\n\n Press, for example, the button number 1 of your remote control. You should get some information about that key in the Serial Monitor. Save the “command” value for that key.<\/p>\n\n\n\n
