What did you use for a keyboard? I don't see it listed in the parts list. Also where did you get it from? Great instructable!
Hi, great tutorial. I have a problem getting my HC-05 to flash rapidly so it can be linked to either my laptop or tablet. I have used several tutorials and was able to connect it up to a arduino UNO and change settings on the bluetooth device in the serial monitor. When I unplug the key wire the led goes off. I unplug the power to bluetooth - wait - then plug it back in leaving key wire unplugged but the led does not come on and my computer can't find it. Help please. My bluetooth settings are: Name: HC-05, Version: 2.0-20100601, Role: 0 slave, ADDR: 2016:1:64004, UART: 115200,
Great instructable. I just received a 2 relay module and needed to test it out before I put it to use. It works great, and this was a big help since I'm fairly new to Arduino. Buy the way I ran the code on a Arduino Nano V3 without a hitch.
