Week 5- Journal

When I heard the buzzer sound for the first time I remembered the ambulance sound so I searched on Google to make ambulance car with cardboard

I used TINKERCAD to simulate the circuit before I started to Build the circuit on a breadboard.

I connected ground of power supply with negative of led and negative of buzzer to connected in parallel.

In positive branch of led connect 220 ohm resistor .

To connect switch in the circuit should connect in series with other components, So we connect positive of power supply with branch of switch and the other branch with positive of buzzer and resistor.

stimulation of circuit on tinkercad.

we have two output

1. the LED light

2. the buzzer sound

I built the electrical circuit in tinkercad but it didn't work, so I tried to check the connection but I didn't work either, so I reached out to Maram to try to fix the problem. Maram is the most helpful person I've ever met. Maram proposed making an online meeting to solve the problem and we built the circuit again and finally it works.

The second problem is that the switch controls only in the bulb not in the bell either, this problem is because I connected the key with the bulb in series and left the bell.

Maram explained to me that the current must pass or enter the key before sharing it to the bell and bulb
