Are parts have arrived today , which means we can start putting together the stress ball using bread boards before we turn it into a prototype.
We now have 2 heat pads and 2 pressure sensors, we went against having to vibration motors to try and save costs , as I already have a vibration motor we will just use that one.
One photon and the small pressure sensor will be put into a ball for the prototype, ether a stress ball or a tennis ball. That will be the emotion detector.
The big pressure sensor will be on the other photon on the chair, which once sat on will send a message over MQTT to node red to say "someone has sat on me what's there mood like"
Node red will take the ball readings and work out their average mood over the day , then send the emotion back down through the MQTT topic "vibration"
raspberry Pi is listening on topic vibration for an emotion , once received it kicks in the emotion relaxation commands to help relax the user.For the prototype we are using 2 pre defined commands for emotions , in the finale product the user would of customised what happens based on there mood
Ardunio receives a serial command from the pi telling it what to turn on and off
