Problem
I have to create a sound circuit. The sound circuit must create a sound. There are a assortment of sounds that I can make my circuit emit at my disposal using the Electronic Playground pdf provided by Mr. Cepeda. The materials that must be needed for this project are a transistor and sound transformer, I can choose to include some LED'S and a some capacitors. I must follow the 12 steps of the Engineering Process in my journal. We must have at least 1-3 planning ideas in our journal. We also must create a virtual testing to test the project, we can do it on Tinkercad or Multisim. This will help us get a good visualization of what and how this circuit will work. There are sounds provided in the pdf but we don't have to do all of them that was given to us. To make it a little easier for us on our part, we can use the schematics that was also provided in our pdf that is going to help us complete our project. It will basically take us step by step.
Solution
So in this project, I was planning to make a woodpecker circuit to emit my sound. I had a little problem and it was that I wasn't able to gather the supplies that Mr. Cepeda had stressed to obtain. Not because I was lazy or I forgot, I simply was not allowed to. My parents didn't allow me to gather or order any supplies so I was forced to make do with what I had. The only alternative I had in mind was creating my circuit online using either TinkerCad or Multisim. I had no experience in both so I watched some videos that helped me understand what was what on both platforms. Initially, I planned to use TinkerCad to create my circuit because of its simplicity. Another reason was because it had actual images that helped me sort things out on my circuit compared to Multisim which only had symbols. I used the schematic provided inside the pdf to create the circuit. There was another problem I encountered while working on TinkerCad. It didn't have some components needed nor could it split wires. This means that I couldn't connect multiple components with multiple wires. I tried to search up workaround for this problem but that came up with no avail. After an hour and some long minutes, I decided to move to Multisim. Surprisingly, it had the solution to my previous problem. It had a transformer and could split wires. I then recreated the schematic to the best of my ability. It came out well with the exception that it didn't have a control or speaker so I used a switch and buzzer as alternatives. After creating my circuit, I tested it and it didn't work. I tried using different components but it still didn't work. Perhaps I had the values wrong? Maybe a resistor had too much ohms on it. I checked and compared the schematic I had created with the one given to me, and the values seem to add up. Maybe there was an error in my circuit? Multisim has a troubleshooting section that tells me if there were any errors, I checked and there was nothing that came up.

Feedback
This project was dubbed as the "Hardest project in this quarter" by Mr. Cepeda and for me, it still stands. Even when trying to meet the requirements while considering the constraints, it's pretty difficult. I'd imagine doing this in an actual school session rather than online would be mush easier and if not, at least easier to get a grip on the project at hand.
