openledcontrol
Build a light-activated LED controller, from an LDR to a transistor switch, in three sessions.
- Session 1: A sensor, a decision and a switch (Level 1, 60 min)
- Session 2: The divider, the LED resistor and the transistor (Level 2, 75 min)
- Session 3: A controller you can trust: hysteresis, tolerances and logic (Level 3, 90 min)
