These days we have focused on transforming the breadboard circuit into a solderable breadboard circuit, adding a small box to enclose everything.
Here is the result of prototype #2:
As you can see, all components used on prototype #1 are in prototype #2. We have added a little led for debug (bottom right) connected to the mosfet pin.
The circuit inside the box:
We have added two usb connector for USB IN and USB OUT, fixing with hot glue:
By connecting the circuit to the actuators, to the photoresistors and to the solar panel we obtain this beautiful result to see:
Now we are ready to do some tests outside.
