1.	How many terminals does the rotary encoder have?(a) 1(b) 3(c) 5(d) 4This question was posed to me in examination.The above asked question is from Rotary Encoder in division Interfacing of Sensors, Actuators, and Other Modules of Arduino
Answer» RIGHT option is (c) 5 To EXPLAIN I would say: The rotary encoder has 5 terminals which include the Vcc for power SUPPLY, the CLK for clock, DATA which provides us the output wave, and SWC which switches voltage to 0 and GND which is required for completing the circuit through the sensor and GROUNDING it.
