Week 10 - Changing the LCD module and Power Supply.
After the new 5V AC to DC power supply and LCD module arrived, I disconnected the damaged LCD and plugged in the new LCD module. The pins connection is just the same as the previous LCD module. Then I connect the 5V power supply to the power jack of the Arduino Uno board and turn on the supply. The LCD worked and I waited for the GSM to establish a connection to test the project. The project runs smoothly as intended. In conclusion, the 5V power supply is sufficient for the project to run.
