Assalamualaikum and hi! β
Week : 7
Date : 1 Sept 2019 - 7 Sept 2019
Activities :
1. Testing sound sensor capability - Serial Monitor Arduino IDE 1.8.9
π 1 September 2019
π By using the same circuit for testing the sound sensor capability, coding of the test is improvised a little bit to show the low and high condition of the LED when the sound sensor detects sound. The serial monitor of Arduino IDE 1.8.9 will print out "Sound detected" and "Sound undetected" based on the coding that has been written and uploaded into the Arduino UNO board.

π Based on the coding, the declaration of a pin is vital so that the Arduino UNO board can interpret the data. When the sound detected by the sound sensor (in HIGH condition), serial monitor of Arduino IDE 1.8.9 will show "1" and "Sound detected" or otherwise (in LOW condition) it will show "0" and "Sound undetected".
Sound sensor >> HIGH (detect sound)
LED >> HIGH
Serial Monitor >> print "1" and "Sound detected"
Sound sensor >> LOW (does not detect sound)
LED >> LOW
Serial Monitor >> print "0" and "Sound undetected"

2. Configuring signal conditioning circuit
π 2 September 2019
π A bandpass filter is chosen as the signal conditioning circuit for this project because to limit only a certain frequency of sound that the sound sensor can capture. An inverting bandpass filter is designed to have a much narrower passband. The frequency and bandwidth are related to the values of the resistor (R1 and R2) and capacitor (C1 and C2). The output of the filter is taken from the output of the amplifier.

3. Pitching Technique Workshop
π 4 September 2019
β 3.00 pm - 5.00 pm
π¬ TTL 1
π Speaker : Mr. Rostam Effendi (Akademi Keusahawanan RiK (AKaR))
π All FYP students were highly encouraged to attend this Pitching Technique Workshop.
π This workshop gave valuable information on the skill, trick and technique for pitching the FYP project.
π According to the speaker, the formula for good pitching is V.O.I.C.E.
π Every pitcher must know the value/benefit of their own project and how to measure and validate the value of the project because a good project is a project that can be commercialised to the others. An idea of a project is actually coming from a problem that needs to be solved. A problem is an opportunity to generate an idea. A pitcher also needs to know what is the unique value of the proposition of the project and how to compare it against other competitors. By doing a project, a pitcher must have already identified who is the target market for the project, how to channel it and plans the cost structure (fixed and variable cost).

β 12.15 pm
π¬ SPS 209
π Constructing of signal conditioning circuit on a breadboard to see the functionality of the circuit.
π Supervisor asked to collect the data as soon as possible and develop the prototype as small as it could be.
π Supervisor said it is better for the filtering circuit if it has succeeded to be constructed on stripboard or PCB board so that it is much smaller.
