WEEK 7 (FYP 2 )

WEEK 7 : Test Servo Motor

OBJECTIVE :
To test the functionality of servo motor.

METHODOLOGY :
1) Set up coding for this part.
2) Set the virtual write inside coding.
2) Set up circuit with the right connection.
3) Connect NodeMCU with WiFi by using blynk application.

RESULT :

Video 7: Servo motor is function well.

Figure 31: Set up slider inside the blynk application

Figure 32: Make sure the value of output is between 0-180

Figure 33: Set virtual based on coding

ANALYSIS AND DISCUSSION :
Servo motor have 3 pins. The first pin is connected to ground.The second pin is connected to 3.3V NodeMCU while the third pins is connected to D0-D8 nodeMCU. The blynk must be set up correctly based on coding. For example, if one of three pins for servo motor was setting as D0 inside the coding, we must also set the virtual for the pins so that the blynk application can read the virtual to get the servo motor can be function.

CONCLUSION :
Make sure all the step has been set up correctly. If not the motor will not be function.
