Introduction:

The goal of ICP2 was to read a heart beat and transmit over Wi-fi to thingspeak using their API, for graphical visualization.

Approaches/ Methods:

• First we needed to correctly wire the lcd to the Arduino and display a message to confirm the connections were correct, then display heartbeat of an individual onto the screen. • Second we had to create a connection via Wi-Fi between the Arduino and thingspeak using an API. • Last we connected LEDs that would light within certain bpm ranges.

Workflow:

First we connected both the lcd and heartbeat monitor through trial and error. After getting the correct connections. Wi-Fi connection was made through a hotspot, after which we used the thingspeak API to transmit data into a channel. Last we integrated ICP1 to light an LED to correspond with certain bpm values.

Circuit Diagram:

Parameters:

• LCD prints Group 1 on setup • Wi-fi was changed to connect to a specific hotspot, and use a thingspeak write API key • We added code for LEDs to light when certain bpm values are reached, (bpm>170 = red light), (bpm<100 = green light) • Coded added for ICP bonus.

Evaluation & Discussion:

There were some confusions on how the lcd was supposed to be wired, and there were major difficulties in both wiring and connecting to the esp Wi-Fi module. After some assistance with the wiring we spent a considerable amount of time troubleshooting the connection error, only to learn that it were three lines of code missing. The applicable uses we saw were transmitting a patients bpm for observation, to see if its stable and erratic.

Conclusion:

Most of our difficulties and time wasted came from troubleshooting the esp Wi-fi model. We were however able to successful see how data can be transmit to a third party through an internet connection and API usage. Applicable uses a of this can be seen in health, sport, etc.
