I'm going to make improvements on it. Like: Screen where it shows posesions (like a 3d printer) and other info
First question
Is use Adafruit Motor Shield v2. But do i need it? Is there anything easier I can use.
Any suggestion?
Second question
In the code it says: #define SERVO_START_POSITION 90 // Solar panel should be faced south at 90; then 60 is west and 120 is east
Can it find south by itself? Like: Where it goes in a position to be in the south, then he wait. Then I have to physically move the rig, until it says a sound "pipp". and it start to work efter 30sec
Like to add this, if I get it to work (When is the position there sun going up, so i need to change it if I in other country, Like a screen and up/down button and it says: Where is sun going up: )
If there is a lot of work, then I can pay one of you to and fix the code
Knutarn:
(When is the position there sun going up, so i need to change it if I in other country, Like a screen and up/down button and it says: Where is sun going up: )
I suspect a person in any country will know where the sun is at midday and can position the device so it points at the sun with the panel in its centre position. In some countries that will be facing North
I have no experience with that (or any other) motor shield and you have not told us what you plan to do with it. I assume you just want to control a small DC motor so it should probably be OK. Just make sure the shield can comfortably supply the volts and amps required by your motor.
How big is the solar panel and how much energy can you afford to "waste" in the positioning system? To minimize energy consumption it would be better to use an Atmega 328 on a PCB or piece of strip board rather than a complete Arduino.
any tips on controller (on ebay) I can use? And what i need to change in the code
Other
Want to make some changes. Do you have any suggestions? The reason I want it is that it's fun and work with it. So it will not be copy and past from the maker
Like and have a screen. Which shows the servo position and how strong sun is And maybe show a watts and volt solar panel give
