WEEK 3 (FYP 2)

WEEK 3 : Testing NodeMCU (ESP8266)

OBJECTIVE : 

1) To find the right NodeMCU.

2) To Test the blynk application.

METHODOLOGY :

1) Test the Node MCU using serial monitor in Arduino software.

2) Test blynk apps on Android smartphone.

Results :

Video 1 : Node MCU cannot connect WiFi

Video 2 : Node MCU can connected to WiFi.

Figure 28 : Serial monitor from the first Node MCU

Figure 29 : Serial monitor from the second Node MCU

Discussion & Analysis :

In video 1, the first Node MCU cannot connect to the WiFi, while in video 2, the second Node MCU easily can connected to the WiFi. In a picture 1, we can see from the serial monitor in Arduino software, the first Node MCU cannot connect to the WiFi, while in the second picture, the serial monitor can connect to the WiFi.

Conclusion :

We need to test every hardware that we buy to ensure the hardware is working properly.
