Week # 5 - Journal

This week my assignment idea is to design an electronic device 

(Buzz Wire Game).

I have this idea from the attached videos 

the device performs two actions

I always liked this game .

it's  pretty excited when I found that I could actually make a similar one at home 

First of all i used ThinkerCad to make circuit and check it before doing it on real. 

Materials:

• Breadboard mini .

• on/off switch

• Buzzer

• Red Led

• Resistor

• Jumper wires

• Crocodile wires

• 5 Volt adapter

• Cardboard (my Shaving cream box )

I start to create the design and simulate the circuit using Tinkercad to make sure   they all ok 

then I used 5 voltage power and connect it by the jumper wires on the breadboard to make them shorter, in order to keep the circuit clean and easier to debug for problems and the 220 ohm resistor

Then i put the switch and connect it with led and the buzzer . the type of circuit parallel  

the output led and Buzzer 

I used 5 voltage power because  the Operating Voltage for Buzzer : 4-8V DC  

Buzzer AND led JUST NEED FOR 21 A

After i finish sketching in tinkercad i started to make it in real. I put the red led and the 220 ohm resistor in series and the buzzer parallel to them then i connect one of the sides of the switch to the positive wire and the other side with the hand of the game and i connect the wire of the game to the buzzer and led with crocodile wire . Finally i put all the components in the cardboard i made . 

I faced a challenge after closing the project

And when I tried it, I found that the opening and closing button does not affect

In other words, when the electricity is connected, the game works even if the button is closed

The connections have been placed in such a way that the circuit works whether the switch is closed or open

I opened the box again and looked for the cause of the problem

And I reached the solution through experimentation

I connected the red voltage wire to the switch And make the circuit cut off in the case of the switch closed and vice versa

I made several attempts until I succeeded
