Activity 1~

Basically, there are two main difference between this module and the module last semester . First and foremost, all the activity or lesson in this module will be finished before we start on our main project. Another major difference is the amount of research that has to be done before we decide on what we are going to do for our project but this semester we will be given two options and we choose one among them.

After the brief introduction, we start our first activity for this module. Each group is then assigned a type of sensor and our task is to design a circuit to indicate the output of the sensor. Before getting the sensor, each group get a LCD from Miss Rubaina and we have to make the LCD monitor work properly. Our group face some problems when we are trying to function the LCD monitor. However, we manage to solve it after a thorough check on our circuit connection. The main cause for the mistake is the wrong connection of a wire to the LCD monitor.The second problem which we encounter is that we are unable to upload the codes to the Arduino board. This is because we forget to select the correct board and also the serial port at our computer. Thank to our lecturer,Miss Rubaina for reminded us about our careless mistakes thorough the activity.

After that, each group gets a sensor and our group gets a temperature sensor. Once we get the temperature sensor, our awesome manager, Sean wants to put the sensor into his mouth. Fortunately, he stops it when Miss Rubaina tell us that previous students used to put the sensor to test the temperature in their armpits. Oh my God! I can see the stunning face of Sean, he quickly throws away the sensor. We then connect the sensor to our LCD monitor which we have done earlier. Besides, we also modify and combined the code for the LCD and temperature sensor together. We test our circuit with hot water and with cold water. It is very interesting when we find out that the circuit is working well. Lastly, we add two different colour of LED (red and green) and a buzzer to our circuit to make it multifunctional. We code the program in such that when the temperature of water exceed  30 °C , the red LED lights up and the buzzer will produce sound while green LED lights up when the temperature is below 15 °C.

The circuit connecting to the sensor.

The completion of the activity marks the end of our first lesson in this module. This is a good start for our group as we complete the first activity successfully within the lesson period. It is a fruitful day to all of us, I believe, as we have all learnt something new about the amazing things that we can do by technology nowadays. Last but not least, we want to say that even though we are at disadvantage on the number of people in group, we will not give up and work harder as a team because we believe that “ TEAMWORK makes the DREAM WORK”! We are looking forward for the lesson next week. See you guys next week! BYEEEE~
