3. CONTENTSI. About the manipulator EIO interface II. Basic knowledge of electronicsIII. Flashing LED lightIV. Skills competitionV. Classroom summary
4. I. About the manipulator EIO interface
5. 11What is EIOEIO（Extended I/O）
6. 2Role of EIO interface
7. 13Details about EIOEIO address of the jib interface boardGND: wire grounding terminal5V: 5V voltage terminalADC/PWM: two signal processing modes, which also can be set as 3.3V level input/output terminal
8. II. Basic knowledge about electronics
9. 11Analog signalDefinition:The information parameters shows continuous signal in the given range, or in the period of continuous time intervals, the characteristic quantity of the representative information can be presented as signal of any value at any moment.Analog signal
10. 2Application of analog signal你知道模拟信号有哪些吗？Sound Temperature RainfallWind direction and forceHourly weather of southern suburb, BeijingLatest hourly actual temperature: 31℃relative humiditytemperaturemaximum 32℃: minimum 21℃
11. 13Digital signalDefinition: he value of the amplitude is discrete, and the amplitude is limited to a limited number of values.Pulse levelDigital signal
12. 4Application of analog signal你知道数字信号有哪些吗？Digital cable TV signal, mobile phone signal, broadband signal, etc.Fig. 12-1
13. 15What is PWMPWM (Pulse Width Modulation) refers to the pulse width modulation. The high and low level time of the square wave of the signal can be adjusted, which is called the duty ratio and usually can be set to 0%~~100%Fixed cycleFixed cycleFixed cycle
14. 6Electronic components
15. III. Flashing LED light
16. 11Light Emitting DiodeLED in short, which converts electric energy into light energy.The long pin is connected with the positive and the short pin is connected with the negative
17. 2Connect LED to the manipulator 1EIO addressingLevel
18. 2Connect LED to the manipulator 2Connect the positive of LED lightConnect the negative of LED light
19. 13Programming Step 1: set EIO7 interface as 3.3V level outputStep 2: view the value of EIO interfaceStep 3: set the value of EIO7 interfaceStep 4: run the program
20. I control my manipulatorOperation purpose: the manipulator expansion exerciseOperation task: light up the LED
21. IV. Skills competition
22. It is time to operate by yourself!
23. I control my manipulatorOperation purpose: the manipulator expansion exerciseOperation task: two LED lights flash
24. Program exampleThe red LED light is connected to GND and EIO5 at the third interface of the jibThe green LED light is connected to GND and EIO7 at the second interface of the jib
25. I control my manipulator - expansion exerciseOperation purpose: the manipulator expansion exerciseOperation task: the LED light with sound effect flashes
26. Program exampleConnect the positive and negative of the buzzer to EIO9 and GND pins at the first interface of the jib
