Hey. I'm trying to build a keyless entry system for my dorm room...I was thinking about trying to connect the output of a makeymakey to an arduino pin and then just set the arduino pin as an input: if that pin is high then move a servo to turn the lock. However, I was wondering if this is actually feasible? and if so do I need to do anything additional to get arduino to recognize the makey makey or otherwise how I might go about doing this? The makeymakey says the output is just high(5v) or low and I tried connecting it to an arduino earlier but with no luck. Thanks for any help you can give
We need a link to the device.
Hey, Here is a link to the makey makey: http://makeymakey.com/
From looking at the video, it looks like the device has a USB output to a PC. I cannot see any advantage of this device over normal Arduino and sensors.
I would go for something like an iButton, totally unique code in each button.
Or wireless card reader.
The MakeyMakey is gross overkill for this project. Touch sensor modules cost just a few dollars on eBay.
RFID kits are also very cheap.
I am not sure where you are going to get a sufficiently powerful servo to turn a lock.
