Is there a help page for this? Having issues with up/down tracking. It does reset back to flat on reset but never changes angle after initial setting.

Hi, may I ask if you have reset the servo according to the installation steps (part 11) and then installed it? If not, you need to remove it, reset the servo, and then install it back; if it has been reset, it is still the case, please use the program in Lesson 9 in our tutorial to test the servo separately to see if it can work normally, and control up/down The tracking servo is on pin D10, just change the 9 in the program to 10 If you still can't solve the problem you have encountered, you can contact us through Amazon or our after-sales mailbox

I was hoping someone can send me the full code for the solar tracking since i cant get it to work and i tried their code aswell and i get an error.

How large is the solar panel and what is the open circuit voltage of the panel?

Size: 13.7*8.3CM, the open circuit voltage of the solar panel is a maximum of 5V, and the voltage varies according to the intensity of sunlight

The it requires a lithium battery, but it doesn't specify the size or type. What model single cell lithium battery is recommended?

Hello, the battery model required for this product is 18650, please buy a flat head (the positive electrode is flat)
