For this week's assignment, after thinking for 30 minutes I decided to go with a fire-alarm, but it doesn't exactly look like this😅
When the place is on fire, the nearest person will turn it on to alert everyone to vacate the building

Tinker circuit
First of all, i started by designing the circuit on tinker cad:
1) connected the 9v power source with a voltage regulator and with two rails
2) connected the dc motor to the two rails
3) connected the piezo in parallel with the motor
4) connected a red LED parallel to them with a 220-ohm resistor
The reason I used 9v source is that the voltage source box when set on 5v is not realistic with the geared motor (rotates slower than in real life)
The circuit connection is parallel, so the voltage is not divided since the components need the full amount

1) Connecting the jack converter terminals to the breadboard
2) connecting DC motor terminals
3) connecting the piezo terminals in parallel to the motor
4) connecting LED positive terminal with the source, and its negative terminal to a resistor connected with the negative side. In parallel of course
5) Moved the positive source terminal to another rail connected with a red wire
6) connected the green wire in the old place of the source positive (to add a switch)
7) connecting crocodiles between the jumper wires and the switch, so now it is connected in series with the circuit
8) Final circuit
9) Laying out components' placement on base
10) Fixing switch and power source port on sides
11) Poking motor shaft hole on the other side
12) Assembling four sides of the prototype by glue gun
13) Fixing motor to its place by tape
14) Fixing LED in place on the ceiling
15) Fixing the breadboard by tape and both the adaptor port and power switch in their places
16) Adding a plastic bulb-like cover on the top
17) Placing an emergency flag to the motor

The switch is used to turn the alarm on and off
The buzzer makes a sound
The LED gives a red warning light
The geared DC motor rotates a flag as a sign to evacuate

Overcoming Challenges
When you got stuck, what/who did you turn to? At what point did you have to pause to research or learn more before moving on? What are some mistakes, pitfalls, or challenges that others can avoid if they were doing this assignment?

I placed the power input just up to the cylindrical part, so when i tried to connect it with the adaptor it fell inside.
The solution was to just push it further up to the rectangular part to hold in place and avoid slipping
