1  Using Arduino / Networking, Protocols, and Devices / Re: How to get the JY-MCU bt board to work on: January 18, 2013, 03:29:01 pm
I had the same problems where only the AT command received a response. I have the breakout version 1.03 with firmware version 1.5. Found and changed a simple Arduino sketch to allow AT commands to be sent to the Bluetooth adapter. Simply adding a delay(10) allowed the other commands such as AT+VERSION to get a correct response from the Bluetooth adapter. I used Arduino's serial Monitor to send all the commands.  This is based on the code in the link provided earlier in this thread. Hope this is useful to some!

Link to the code:

I have the same problem with AT commands, only have AT working, non other. Is the problem in the software serial sketch maby? I don't have a usb to ttl board, only a usb to rs232 so I really need make it work over the arduino, any Ideas?

This code worked for me!! Thank you very much! I had to change BAUD rate to 9600 for BT and 57600 for arduino comm. Then in serial monitor baud 57600 no line ending. I am now controlling my lights via bluetooth! Thanks so much!

Hi all,

I am trying to setup my arduino to switch on an off a light with this relay:

I have hooked it up and the LED on the shield blinks when I use my code, But I do not know how to wire my output for my light.

There is a spot for an NC (normally closed) NO(normally open) and a C. I am not sure where I put my positive and negative to wire the whole thing as a circuit.

Any help would be greatly appreciated.

Thank you for the replies! After reading some of the code on that website, I realize that there are methods for assigning duties to the pins such as INPUT and OUTPUT. Seeing that was a big help in me understanding the syntax of how the software interacts with the hardware. I am going to buy a beginners pack online and that kit so I can use it when I am ready. Are their any kits that you would recommend for a starter?

Hi all,

I am new to arduino and am about to buy one for the first time but I have a quick question. I am in this for the long run so I am planning on buying a starter kit and some sensors. I came across this . My question is,
if I buy these sensors, how do I read them? Is there a certain place I could find some general code? Some of them I googled and I could find code but I am wondering if there is some general code to read analog sensors.

Thank you in advance for your replies,
