KY-018 Photoresistor Sensor

2 Comments

The KY-018 board is equipped with a light-dependent resistor and a corresponding current-limiting resistor. Data: Voltage: 3V-5V (other voltages are conceivable) Output: analogue voltage value I suspect that a GL5528 has been installed here. Facts: Connection designation – Ground + V+ (3V-5V) S Signal KY-018 – Pin assignment View Application areas: Brightness measurement As a sensor for aligning solar cells Light barrier as...

CodeShorty: Wire Scanning (Uno)

Leave a comment

The I2C, also known as the 2-Wire bus, works with two wires and theoretically at speeds of up to 5 Mbit/s. For hobby use with open-air wiring, it's likely to be less. The Uno has the Wire connection on analogue outputs 4 and 5. To test, I connected a GY-68 barometer which is on port 0x77 of the...
