“Roald Dahl wrote a short story named The Sound Machine. There, an inventor named Klausner develops a machine to hear plants painful shrieking noises when they are cut.
Based on that idea I’ve made The Klausner Machine. In this case sounds are generated according to plant soil moisture conditions. Dry soil -> pain sounds Humid soil -> happy sounds
Supplies:
1 Arduino Nano
1 Soil Moisture Sensor
1 DfPlayer Mini
1 MicroSD Card
1 4Ohm Speaker
2 Analog Vumeter
1 Led
1 Switch
1 Button
Some cables”
