We received the O3 sensor! 😊

During this session, we tried both sensors (CO and O3) on a same circuit.

As the first test with the Arduino Leonardo went well last time, we decided to try on an Arduino pro micro. To connect both sensors we used a breadboard. You can see the circuit below:

For the code, we added some lines. We created a second variable for the O3 sensor. In the EEPROM memory, values from both sensors are alternating line by line.
