hey all im getting my stuff done pretty good but i have a question does anyone have experience with the premade fast spi sample from funkboxing? Im only using it because im short on time but i have a arduino mega adk with a usb host and im trying to figure out how to use the bluetooth dongle with it. If i cant do that I need to find some way to control it maybe an ir remote or something.
All the samples on funkboxing are awesome! They have taught me a lot. What issues are you having with the bluetooth? I might be able to help you… I think the guy who wrote the code is a member here.
well i have the code running but the new one works with a software serial bluetooth and i dont have one but what i do have is an adk with a bluetooth dongle and i dont really know how to make them work together haha
What bluetooth dongle do you have?
a little chinese class 1 i belive but i dont know if the new classes are suported yet
You can buy a JY-MCU bluetooth for cheap I think I paid like 7.00 for mine.
But where? I kinda need it by Friday haha
If you have a car alarm with an open aux channel you could power on and off the arduino with a relay. Just a thought going back to my car stereo and alarm install days.
isnt that normally 12v?
All car stuff is 12v
thats what i thought
Yes the car electrical system is 12v. Relays are built to control other voltages separately from one electrical system… So a relay on your alarm can control another voltage source. Power the relay circuit from the car and control the position with the alarms momentary switch, And connect the power source of the device you are controlling to the other side of the relay. When you hit the aux button on the alarm, the relay triggers and turns on the +5v hit the aux button again and the relay will turn off the voltage supply.
