Arduino Light Sensor Arduino Uno’s pin A0 to A5 can work as the analog input The analog input pin converts the voltage (between 0v and VCC) into integer values (between 0 and 1023) called ADC value or analog value By connecting a pin of the photoresistor to an analog input pin we can read the analog value from the pin by using analogRead() function and then we can know.

Grove Ultrasonic Distance Sensor Seeed Studio

Compared with traditional ultrasonic modules HCSR04 the Grove Ultrasonic Distance Sensor integrates a singlechip microcomputer and the transmitting signal and the receiving signal share one pin by timedivision multiplexing so only one I/O pin is occupied Another difference is that HCSR04 only supports 5v voltage while Grove Ultrasonic Distance Sensor supports 5v and.
