C. Discussion In constructing the device and to perform programming task, this paper has faced some difficulties such as developing the software, testing the experiments also in troubleshooting parts. The infrared LED must be light if it is functional. By use phone camera, it can recognize either infrared LED functional or not. If the light appears when see it on the phone, so it is function. Encountering this problem is by changing the position of the feet of infrared LED. Then, the critical part is to design the coding of pulse oximeter in MATLAB coding programmer. The declaration of each component in the ADSP board must be right. If the declaration is wrong, the sensor can’t detect the value, thus the reading will be wrong. Furthermore, in building the MATLAB Graphical User Interface, there were some problems to encounter. Each block diagram has the own properties and purpose. The diagrams have to be structured very well to prevent the error. The port to interface with

Arduino board must be correctly connected in Serial COM port number. Hence, the paper has their pro and cons in making the perfect device.
