Basic Level
- Practical case: Object counter on conveyor belt
Master Analog Electronics by building an optical barrier with a Photoresistor. Detect moving objects and trigger a precise logic signal when the beam is broken. - Practical case: Simple light intensity meterMaster Analog Electronics by building a dark sensor with a Photoresistor. Create a circuit where an LED automatically dims in bright light to save power.
- Practical case: Secret drawer alarm sensorMaster Analog Electronics by building a drawer alarm. Use a Photoresistor to detect light and trigger a buzzer instantly, securing your valuables effectively.
- Practical case: Automatic twilight switchLearn Analog Electronics by building a dark-sensing switch with a Photoresistor. Create a circuit that automatically turns on an LED when ambient light drops.
