Lesson 43--Microduino Rotary encoder

Language:	English  • 中文

Objective This experiment will through Microduino to decode the rotary encoder, judge the movement direction and whether it was pressed. Equipment Microduino-Core Microduino-FT232R Other equipments Rotary encoder USB cable Breadboard Jumper Breadboard Rotary encoder Rotary encoder This kind of rotary encoder has turn left, turn right and press three functions. The function of the press just like we use the button. Rotate the encoder, it caan produce the pulse signal that has a different phase, which can be used to distinguish the opposite direction. If the output 1 as the high electricity level, and a high level in output 2 too, then switch rotated as clockwise, otherwise output 2 is a low level, it must be counterclockwise. Pin Diagram Schematic Program Download test program: https://github.com/Microduino/Microduino_Tutorials/tree/master/Microduino_Advanced/Microduino_rotary_encoder Debug Step 1: Set up the circuit follow the schematic Step 2: Download test program Step 3: Open the test program, select the board and compile the program, then download it. Configure the serial baud rate and open the serial monitor Rotate and press the button, observe the date Clockwise rotation Counterclockwise rotation Press the button Result According to the serial port monitor returned data to judge the state of rotary encoder. The players can make other application based on this experiment. Video
