WEEK 19: COMPONENT TESTING

OBJECTIVE

1. To test each component that have been bought.
2. Testing it's functionality and connection.

METHODOLOGY

1. Test the functionality for each component. The Arduino Pro Mini is soldered with male pin header strip black. A blink coding is uploaded to test if the arduino is working.
2. For servo motor, it is connected to the arduino Pro Mini that have been upload with sweep motor coding. All the servos is function.
3. An ESP8266 blink code is uploaded to the NodeMCU to test it's functionallity.
4. A power supply battery is connected to the input of MB102 Breadboard power supply and a multimeter is connected to the output to measure the correct voltage output. 

RESULT

1. The arduino Pro Mini can be uploaded with the coding from Arduino IDE software and the testing result is as expected. 
2. All the servo motors turns according to the code sketch from the arduino. 
3. The NodeMCU have been test using blink coding for ESP8266, and the light from NodeMCU blinking as commanded. 
4. The output voltage from breadboard power supply is measured using multimeter and the readings is the similar to the stated voltage output on the board.

ANALYSIS/DISCUSSION

There are slightly problem when trying to test the arduino Pro Mini since the arduino Pro Mini must be program using FTDI to connect to my computer, but after I buy the CP2102 USB to TTL to connect the Pro Mini to the computer the test can be carried out.

CONCLUSION

All the components have been tested and the result from the test is as expected. The components are working perfectly.
