🌱 Smart Plant Monitor with ESP32 in Wokwi

  1. Open Wokwi Go to 👉 https://wokwi.com Start a New Project → ESP32 . 2. Add Components From Parts panel , drag: ESP32 board DHT22 sensor (temp + humidity) Potentiometer (to simulate soil moisture) LED (for alert) + 220Ω resistor 3. Wiring Potentiometer (Soil Moisture sim) Middle pin → GPIO34 (Analog input) One side → 3.3V Other side → GND DHT22 Sensor VCC → 3.3V GND → GND Data(SDA) → GPIO15 LED Long leg (anode) → GPIO2 (via 220Ω resistor) Short leg → GND 4. Code (ESP32 in Wokwi) Paste this in the code editor: #include "DHTesp.h" #define DHTPIN 15 DHTesp dht; void setup() { Serial.begin(115200); dht.setup(DHTPIN, DHTesp::DHT22); // choose DHT22 or DHT11 } void loop() { TempAndHumidity data = dht.getTempAndHumidity(); Serial.print("Temp: "); Serial.print(data.temperature); Serial.print("°C | Humidity: "); Serial.print(data.humidity); Serial.println("%...

🔑 Key Points  🧠 Cognitive Revolution: Our ancestors gained the ability to imagine fictions—religion, nations, laws—allowing large-group cooperation. 🌾 Agricultural Revolution: Farming trapped humans in harder lives with more food but less freedom and more social inequality. 💰 Money = Shared Myth: Currencies are trust-based systems enabling cooperation among strangers, foundational to economies. ✝️ Religion & Empires: Unified large populations under common values; both were tools of control and identity. 📚 History = Stories: Human culture is built on intersubjective realities—beliefs that exist only because we agree they do. ⚙️ Scientific Revolution: Knowledge for power’s sake emerged, driving exploration, capitalism, and technological empires. 💼 Capitalism & Credit: Capitalism thrives on future faith—credit systems fuel innovation but also dependency and inequality. 🌍 Globalization: Modern humanity is a unified global network, but cultural homogenization and ecologic...
