Completely new to this game so forgive the stupid questions. Apologies if this is in the wrong forum, unable to find anything that suggests requiring circuit help. I'm trying to trigger my RF device via IR but I couldn't find a consumer product that works on the frequency I need so I decided to DIY it. What I have here is the original RF remote and an Arduino IR module from: https://www.aliexpress.com/item/1-C...Module-Board-For-Home-Device/32859235113.html I figured I need to connect them by soldering the CK and COM to both sides of the contact switch on the RF remote: My questions are as follows: 1. The module seems to do maximum 10A output while the RF remote seems to use a 23A battery. Do I need some form of resistor or complex circuit or will the shortness of the connection (single burst) prevent anything from blowing? 2. Is it sufficient to simply solder a 5V USB cable (I plan to strip this https://www.aliexpress.com/item/100...Barrel-Power-Cable-Connector/32923383877.html) to the VIN/GND ports? 3. Is there a way to replace the battery on the RF remote with the same USB power supply via some circuit or does the 23A battery suggest that it requires too big of a current burst for it to be viable via AC? Details about IR module for quick reference: 1 Input voltage: 4.5-5V 2 VIN: power supply 5V+ , GND: power supply 5V- CK=normally open, COM=common, CB=normally close, all of these three ports connect with output. 4 Working Mode: Self-lock control (Press the button on remote, then relevant Channel of the relay module will work. press the button once again, then it will stop.) 6 This switch receiver can learn nearly all the NEC format IR remote control transmitter.
