-A relay module is a component that contains relays, which are electromechanical switches. It uses an electrical signal to generate a magnetic field that opens and closes mechanical contacts, allowing control of devices like light bulbs or garage doors.
How can Arduino automate a garage door opener?
-Arduino can automate a garage door opener by using a relay module connected to the opener's terminals, which simulates the pressing of a button to open and close the door.
What is an infrared (IR) remote control and how can Arduino interact with it?
-An infrared remote control sends codes in hexadecimal format to control devices like TVs or air conditioners. Arduino can clone these codes using an IR receiver and then send them back using an IR LED to automate the device.
What is the purpose of the IR receiver mentioned in the script?
-The IR receiver is used to capture the hexadecimal codes sent by an IR remote control. These codes can then be programmed into Arduino to replicate the remote's functions.
How can Arduino automate devices that use remote controls?
-Arduino can automate remote-controlled devices by cloning the IR signals from the remote's buttons and then sending these signals using an IR LED to control the device.
What is the 'irremote' library used for in Arduino?
-The 'irremote' library is used to read and send infrared signals, enabling Arduino to interact with devices controlled by IR remotes.
What additional resources are available for learning more about Arduino home automation?
