This week's assignment is to design, simulate, and build a simple electronic device that performs two actions .
I choose the buzz wire game because I’ve been playing it since I was a kid so it’s so nice to know how to make it myself now.
Reference
Electronic Copmonents:
I started with simulating the circuit in Tinkercad to make sure of the connection.
- connect the power supply with the breadboard and union the ground and power.
- connect on/off switch with the power.
- connect the led. leg to the resistor to power and the other to ground.
- connect the buzzer to the positive and ground.
- Add the cupper wire between the switch and positive.
So now I have one input (on/off switch) and 2 outputs (buzzer and led). And the circuit is connected in parallel for optimum load efficiency.
parallel connection was optimum since it preserves the voltage drawn by each output load item and in the same time allows each component to run at it's optimum.
I chose 5 volt because it is a voltage level suitable for this application since the lamp works on a range from 1.8 to 3.3 volts and the buzzer range start from 3 volts.

Start to build the circuit and test component by component.
After building the circuit as Tinkercad and union all positive and ground connect the adapter ground to the breadboard ground and take the positive of the breadboard to a crocodile alligator from side and the other side to the cupper wire then take another alligator from the switch to the cupper hoop. so now we opened the circuit with the cupper wire and hoop so since they touched each other the circuit will be closed and the buzzer and led will be turned on.
Start to build the card board enclosure and mount the components inside as fellow:
-Put the breadboard on a cardboard to take the size and make the base.
-cut the front with the same width and assembly with the base by hot glue and support by triangle brackets.
-cut the side and make a slot for the switch and adapter socket in by thier dimensions.
-make the other side and make a hole to the regulator that connected to the cupper hoop.
-attach the top and make a hole for led to go through and and 2 holes too to fix the cupper wire.
- close all by the back.
During powering the circuit in the enclosure it doesn't work so I try check the circuit to troubleshooting and found that a crocodile connected to the the switch was detached so I connected it again and it works.
knowledge and skills I had learned this week will reflect a lot of benefits on the final project, for instance,
