Prj_SoilSensorTest

Triggered by "Digitale-Dinge" (see: www.digitale-dinge.de/blog/episode58_esp32garten for the video) i repeated the earlier setup of Toit/Jaguar in 2022.

If you want to test out Toit/Jaguar on ESP32, you can use these simple examples for your startup.

• 2_adcTest
• 3_soilSensorTest
• 4_mqttTest
• 5 small OLED added, current humidity and history diagram
• 6 firmware improvments: actionRepeater, buttonHandler
