could you tell me if the above is working ?
Also how to use this with the SPA ?
Seems no one has much hope for a poor Uno or similar to handle the sun tracker algorithm
by the way, linear actuators are harder to use than belts and pulleys.the movement using a linear actuator turns the control into a ellipseusing belts and pulleys like the folks controlling telescopes turns the control into a linear function.
If your RTC suffers a power failure the clock will be incorrect. However if the GPS module is power cycled it will establish the time in UTC within seconds. UBLOX modules on eBay are now about $10.
Um, suffers a power failure? A fresh battery is good for several years. Even with a GPS you want some kind of RTC backup because a GPS seek can take as long as 15 minutes if the almanac is wiped.
