Good morning The problem I had was the GPS. I bought the small antenna model and that one doesn't work well... The blue GPS works very well, however, the screen does not show data with this sketch. All the best

Hello Robert, I have built the GPS you designed and I’m experiencing an issue. The OLED screen works, but it doesn’t receive data. The GPS doesn't blink... I have this model: https://es.aliexpress.com/item/1005006523594418.html?spm=a2g0o.order_list.order_list_main.17.792b194dEqoYU7&gatewayAdapt=glo2esp It also doesn't receive anything from EQMOD... Does it seem like the module isn't working? Thankyou

Hi Robert. I have made a focuser with an Arduino Pro Micro + DRV8825 (firmware 330). Everything works well, but I find it strange that, at the end of any movement, a sound can be heard in the motor/driver. Is this normal? Can something be modified in the code? I'm sending a video where you can hear it. https://drive.google.com/file/d/1jHl46D0PQObOcBcNFsVWoxEjMIYNci-5/view?usp=drive_link

parece ser que es un problema de mi arduino nano. he cambiado el pin 2 (DIR) a otro pin y funciona el cambio de dirección. seguirmos probando el sonsor Hall

I have two doubts. a) I have installed the hall sensor, but it does nothing... what should I do? I guess spin until you find the magnet... but it doesn't spin or do anything... b) On the other hand, I have seen that it only rotates the degrees that I indicate in one direction, that is, if I indicate 90º it rotates those degrees, but if I indicate 45º, it does not rotate in the opposite direction, but rather it rotates in the same direction 45º. What can happen? Thank you

Thank you Robert for your time!!!!! I am a fan of yours and I want to continue using your inventions!

Hello, Robert. I'm trying to make the change so it works on an arduino pro micro... but I can't get it to compile. Am I getting into trouble? or is it feasible Sorry for insisting
