Session 2- How Circuits Help Farmers – Potentiometer Simulation in Tinkercad
In Session 2, discover how circuits can model soil-moisture levels using a potentiometer.
Learn how changing resistance alters LED brightness and understand how analog behavior in electronics mirrors real-life sensor readings in agriculture. What you’ll learn:
1) How variable resistance affects current flow
2) Use a potentiometer to simulate wet and dry soil
3) Observe LED brightness as a visual indicator
4) Connect analog concepts to smart-farm sensor designs
