+## Design requirements
+
+Clinostats are usually used in biology for plants, cell cultures, and small animals such as fish.
+
+1 - OpenClino shall be robust to failures to not harm the animals or samples. 
+2 - OpenClino should operate in hot/humid environments such as incubators.
+
+3 - OpenClino should operate as a clinostat or RPM.
+
+At the moment it is a work in progress. I'm not an electrical engineer so this is 12v.
+Be careful with your electronics. 
+At the moment it functions as a clino but not an RPM. The motors can't start a new direction or speed independently.
+
+## Code
+
+The code is work in progress, it requires the following:
+ - control multiple motors.
+ - acceleration.
+ - docs.
