The first day of my interaction lab’s recitation is doubtlessly more than exciting. In the class we were asked to complete some circuit according to the diagram and fulfill the task of electric soldering. The circuit and functions of its components are as follows:
voltage regulator：to lower the voltage to fit the rated power of the speaker as well as keeping it stable
speaker: to function as doorbell
switch: to keep the ringing doorbell under control
capacitor: to keep the supply voltage stable
When I was trying to match the diagram with actual wires, I found it hard to understand the function of the breadboard and the connection between other elements. Following is the first circuit I built, and there’s something wrong with it.
When I’m building up the circuit, I didn’t realize that the restriction has its own direction and I just plugged it in a wrong side, which caused the element became extremely hot. Luckily I fixed it by comparing it to my classmate’s one and was finally conscious of the importance of following the correct direction in a circuit.
The soldering process is also inspiring as its high efficiency and neatness changed my impression of soldering, which is sparking and tiring.
After all, everything I’ve gone through in this recitation is just a glance of the entrance to the interactive art work, but it’s wonderful enough for me to expect to explore more.
