hi. is there any way i can write a program for the voltage to centigrade temperature without having to use “input” and touching the calculator during competition time?
You provide no specifics and expect an answer? What calculator are you referring to? How does your existing program work?
sorry. i am using the ti-84 plus ce calculator with the ti innovator hub and the temperature sensor (LM19). for my program now, i have “input “m = ?” ,m (same for b) and in the mx+b formula i decided to use x as the analog input from placing my temperature sensor in the water. then this mx+b formula will give me the temperature in celsius. i have been trying to figure out different codes that allow me to have the slope and y-intercept without me needing to type it in physically during competition. thank you!

What I would suggest is taking data prior to the competition, recording the the analog input from the sensor as x and the temperature of your thermometer as y. Create a linear regression from this data, and put the m and b values into your calculator.
If you choose to calibrate your device competition day, take a few additional data points with the water they provide you with, and put these points into your regression. Replace the values of m and b in your calculator.
