I am using Arduino for an IoT class (40 students). II have set up a test program to check all sensors and actuators used in the class (we need to recycle for next semester). However, I would also like to check the Arduino's themselves (and also NodeMCU´s) in case some of the units have been broken. II have an idea of testing input/output of each pin to make sure its working - using LEDs and buttons, but if anyone has some ideas to improve testing, it would be great to hear from you. I guess I am not the only one reusing IoT components from one semester to another. It would be great to hear from other instructors in the IoT field.
Best regards,
