hi. i am not really sure on how to get the LED lights and their temperature ranges. i am using the LM19 with the ti innovator hub and the ti-84 plus ce calculator. can anyone give me some help or tips?

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 ...

You can use it during setup time (10 minutes for regional, 20 minutes for state/national).
You will not be allowed to touch it afterwards.

thank you!

hi. for my y-intercept i do not get a value in the hundreds and i tried to use the points in the example to get their equation but it also didn’t work so i am confused now. can someone help me? thank you!

yes

thank you so much!

Make a graph of the equation over the scatterplot. Not just a line of best fit, your equation that’s in your code.

oh ok. got it, thank you!

hi i am sorry again but there is one equation to find the voltage, one to find the temperature, and another equation that converts voltage to temperature?
