A solar-powered tide clock using Arduino tide prediction libraries
Robert Werner has developed a solar-powered tide clock using my Arduino tide prediction libraries (GitHub link) I previously described here and here. The Instructables page shows how Robert used a servo motor to actuate a pair of hands on a dial face. The red and blue hands give you the time of the next high tide and low tide, respectively.
In Robert’s tide clock, an Arduino programmed with the tide prediction library for Anchorage Alaska keeps time with a real time clock (RTC) chip. At set intervals, the Arduino checks the current time, and makes a … Continue Reading
