The circuit was assembled on a strip board that has been cut into a square.Then the components was soldered part by part to see the connection are well functioned.
Testing was done by checking the connection by multimeter.
At first, the number of jumper are everywhere, then, after seeing supervisor a few times,
Sir Zubir helped in arranging the components and give ideas in testing the circuit part by part.
Below are the figure shows the final look on the circuit that has been soldered completely.
Figure shows the electronic part of the project; amplifier circuits
Figure shows the box of the electronic stethoscope with the graphic LCD and arduino
The graphic LCD that was attached on the box was to display the phonocardiogram display of the heart sound. The arduino was attached on the inside part of the box.
Power supply part was attached on the side of the box to make it easier to change the battery.
As conclusion, the troubleshooting towards the circuit were still on going in order to make the project work as stated in the objectives.
