Because why not?
Wiring
Starting from the line follower with OLED example, add three wires to connect the three pins of DHT11 to GND, 3V3 and D8 respectively.
Programming
Change code.py
to be just import ex06_line_follower_oled_dht11
.
Result
The resulting robot is just the basic line follower, but with a funny face on the screen that also somewhy shows the current temperature and humidity.
