IR Communicate

🔴 IR – Communicate – Your “Programmable Remote Control”

What it does: Sends and receives infrared signals.

Send: Control TVs, air conditioners

Receive: Read existing remote controls

 

🧩 Fun Guide to IR Communication Blocks (Clu-blocks Pro)

📡 Important! IR blocks let your robot send and receive invisible light signals — just like a remote control. You can use it to control devices, react to button presses, or even talk to other robots!

🔻 IR Receiving Blocks

#	Block	What it does	Dropdown options	What the options mean
1	setupIRreceive PIN# 2 Socket Type NEC_8 docallback function	Sets up the IR receiver on a pin	Socket Type: NEC_8, NEC_16, NEC_other, RC5	Choose the IR protocol your remote uses
2	IRreceive get command code	Reads data from the IR signal	command, address, raw, pulses	Choose what part of the signal to read — command is most common
3	IRreceive Pause	Temporarily stops receiving	Pause, Recover	Pause = stop listening, Recover = start listening again
4	IRreceive whether receive new data	Checks if a new signal was received	—	Returns true if a new command came in
5	IRreceive timeout 2000 ms	Sets how long to wait for a signal	—	If no signal comes in during this time, it times out
6	callback with: cmd, addr, raw, pulses	Defines what to do when a signal is received	—	You can use the received data to trigger actions
7	println cmd addr raw pulses	Prints the received IR data	—	Great for debugging or learning what your remote sends

🔺 IR Sending Blocks

#	Block	What it does	Dropdown options	What the options mean
8	setupIRsend PIN# 2 Socket Type NEC power 100%	Sets up the IR transmitter	Socket Type: NEC, Samsung, RC5	Choose the protocol your target device understands
9	IRsend command code 0 address code 0 control bit 0	Sends a full IR signal	—	You define the command, address, and control bit manually
10	IRsend pulses code [9000,4500,563,563]	Sends a custom pulse pattern	—	Advanced use — great for mimicking unknown remotes
11	IRsend raw code 0x1234	Sends a raw hexadecimal signal	—	Use this if you know the exact code to send
12	whether the ir transmission is Complete	Checks if sending is done	—	Returns true when the signal has finished transmitting

🧠 Quick Tips for Students

• Use setupIRreceive before trying to read signals — it’s like turning on the ears.
• Use command code to get the button press — most remotes send this.
• Use callback functions to make your robot react instantly — like turning on a light when you press a button.
• Use IRsend to control TVs, fans, or other IR devices — just match the protocol and code.
• Use println to discover what your remote sends — then reuse those codes to send them back!
