Burn out a single diode
It is worth the experiment and time to burn one of the diodes and to show this to the students. It will cost you a couple of cents, this is true, but is worth it. Here is the procedure to burn a single diode.
Connect the diode to have one battery between the cable end, two have two, to have three, four, five. See pictures. In this process, the diode might burn. We say that it "might" because it depends on the diode. There are diodes that are capable of handling the voltage and will not burn.
On the first picture, the diode still blinks. On the second picture, it is now difficult for the diode. In our case, as of recording, the diode we've used has burned out.

Perfect STEM course. Module 1 - Smart Car with Raspberry PI
Disassemble a remote control car. Change the brain of the car with a smart computer like Raspberry Pi. Build a smart device with artificial intelligence that you could control from your phone and that could freely navigate itself in the real world and on the Internet. Use your hands. Develop programs for your robot and your phone. Be curious and invent.
The perfect course lives up to its name. You move through the content, we check it and return feedback to you.
In the end, you should be able to better understand how to program and design smart devices that would make the world a better place. For everybody age 12+, 16+, 21+, 35+, etc. The hardware costs about 150$. It changes through the years so it might take some time for you to find it as Raspberry PI, motor drivers, power banks and h-bridges.. they change. Note that the course was designed to be led by a teacher with a decent knowledge in embedded hardware and software. This, on the other hand should not stop you, if you are curious.

Add a diode to indicate controller power up
On the Disk Image for the perfect course containing our modified Ubuntu Mate version, there are some special programs that will start a diode when you turn on the Raspberry Pi.
