Fluid, Sensor and diagram

Today we worked on getting the heart rate sensor working with the Arduino. A small program was written to check if we could even get input from the heart sensor. (Later, we also tried to get any signal into a digital Arduino pin, this worked well). We suspect the heart rate receiver to be broken.

In addition, today the ordered Ferro Fluid was delivered. After some experiments, we discovered the fluid is soluble with water (!) and in combination with magnets no spikes are created at all. Eventually, we are forced to conclude the concentration of actual Ferro Fluid is too low and probably mixed with water.

These two things are pretty big drawbacks. However, we will continue to look for solutions in the upcoming days.

Next to this a start was made with modeling the system for the combined code (input, translation and output together). This is necessary for convenience of writing the code, as well as efficiency of the program.

To be continued…
