Sensors update week 5

We started off in week 5 with the ‘Mind Flex’. We measured the voltage across the 5 LED’s. The heigher the voltage, the more LED’s light up. This voltage can thus be linked to your brain activity. Low voltage means low activity. The excact values do seem to differ from person to person. We may adjust the pre-installed values on the ‘Mind Flex’  if it turns out this gives better results for our project. We will test this on different users.

We wrote a program that displays the users’ mental activity. A voltage under the value of 0,36 V will be detected as a ‘relaxed’  state of mind. A value between 0,36 V and 0,38 V is regarded as ‘medium’. Any value higher is ‘active’.

With the help of Martin Verwaal we have been able to write a program to read the heart rate sensor. This will give a good contribution to the analysis of the user’s mood.

 

 

 

IMPORTANT

Due to the coming deadline the different sensors will not be combined in a sinlge output to the motors moving the fluid. Instead the three different sensors will produce three different outputs. The brainwave activity is used to move the motors, the temperature sensor will operate different colored LED’s and the heart rate sensors makes the LED’s blink at a different rate.
