+A device to feed fish at the specified time.
+
+## Smart feeder ##
+
+The smart feeder feeds to the aquarium tank at the specified time by rotating the drum of food. The number of rotation is counted by the push button around the axis.
+As was implemented in the smart cooler，ESP-WROOM-02 has a Web interface and Web APIs. By the Web APIs, we can feed fish remotely. Of course, we can set time for the feed.
