Hello all,
I have mix matched some coding and even hired a freelancer to help with the final program but have lost contact with the freelancer and am way outside my level of knowledge now. I am hoping to trouble shot the code I have.
A little background, I have a Nano 33 IOT, it is attached to an HC-SRO4 ultrasonic sensor. I am trying to send the accelerometer and ultrasonic data wirelessly to my computer. The code also has a few formulas in it along the way. Essentially this device will attach to a barbell, when the barbell is lifted it will measure distance traveled, velocity, time, power and a couple other simple math calculations.
I asked the freelancer to have the code start when I put a number into the serial input, this will be the weight being lifted. Which will also be used in some of the calculations down the line.
As of now I believe I am able to connect to my wifi, and get an IP address, I am supposed to put this in a web browser to see the data. The web page never loads. When I type something into the serial input I get a few random Weights spit out and nothing else more.
The code is below, along with some picture references of the serial monitor.
Any input is appreciated.
