I bought some remote control switches, thinking i could replace the remote with an arduino that transmits the same codes. There's libraries out there that do that already

Alas, a simple replay isn't enough. After spending a weeked attempting to find the sequence (and having the occasional success) i decided to change approach, and open up the remote and connect it to a GPIO instead.

  • voltage divider...

    Shiny • 04/25/2016 at 23:51 • 0 comments

    The switches cause the micro to send the signal, when they are pulled low.

    I've hooked up a voltage divider on each GPIO digital pin on the arduino, so about 2.5V appears at the switch, instead of 5.

    This worked for one switch (on and off). THe arduino uno is 5V and the remote is 3V - one i connected all 4 (actually 8) switches, the voltage got to high (4V across the gnd return)

    I'm going to need to level shift this.

  • Opening the remote

    Shiny • 03/15/2016 at 21:27 • 0 comments

    Opened up the remote. desoldered some of the switches. The board in this remote is SHITTY. it desintergrated and the tracks lifted.

    A simple pullup/pulldown won't work here - ordered some mosfets from RS components.

Just bought one of the arlec rc210's yesterday from my local bunnings and tried to listen to the codes using an UNO + 433 Mhz receiver (Seed) but can't pick anything up. Stumbled across the following link this morning - http://www.thebackshed.com/forum/printer_friendly_posts.asp?FID=16&TID=9382 

See if you guys have any luck. Am back home later this week and am going to see if i can transfer those codes into arduino code. If you guys do make progress please let me know.

Cheers,

Trevor

I had a think about going down this path.. I did almost buy the ARLEC device and hook it up to UNO....I went down the path of the ESP8266 with a solid state relay, clearly not as "pretty" as the ARLEC devices but I felt these power units were rather big.  I still might buy one and pull the wall units apart, I suspect there is 3-12VDC in it that can be used to drive the ESP8266 board.  Did you pull one apart ?

  Are you sure? yes | no
