+
+The `TC-Lab` project will be used for the students as a portable temperature controller system to implement several kind of controllers. Thus, the student should develop the next tasks to reach the final goal (main objective):
+
+- Develop the basic schematic
+- Develop the PCB for the `TC-Lab`
+- Test the `TC-Lab` in the Arduino platform
+- Acquire temperature data from heater
+- Develop a regressor and a classifier
