can anyone please help ive been trying for so long
the plan is when i click one of the buttons it should execute the code for the specific plant and it should display the soil moisture in real time
but the problem is the first plant will always execute but will repeatedly display the first sensed input and not the real time input for example: it started at 0%, even if theres water around if the first input is 0% it will always display 0%.
second problem is when i choose the first plant i cant change to the second plant because im stuck inside the loop and idk how to get out.
can anyone help?
thank you so much.
