This week's assignment was to design a circuit with a closure
I was inspired by old tvs which we all had in our homes, when it did't have signal it made this noisey sound and gave some grey screen, I wanted to make such a nostalgic thing as it reminds me of my childhood.
The software
TinkerCad circuits building and simulation online tool
The Hardware
Six Resistances (220 ohms)
ON/OFF switch
RED LED, RGB LED
5V adaptor
two screws adaptor plug
Tabe
Buzzer
Crocodiles
Breadboard
I dragged and dropped the components of the circuit in the design workspace in Tinker CAD
The RGB was parallelly connected with the buzzer.
I used a 5V adaptor because I LEDs and the buzzer doesn't need more than a 5V adaptor, as it gives the proper current for them. Maybe if I used a resistor with a bigger value then I can a higher voltage sourse.
The cathode of the power source was connected to all components as well as the Anode.
The 220 (ohm) resistances were connected in series with the LEDs.
Finally, all components were connected.
Circuit simulation on Tinker CAD can be viewed from the video below
I connected the two halves of the breadboard together with jumper wires to be able to use all of the breadboard.
I made housing for ON/OFF switch, Rosetta, and the red LED on the cardboard
after I finished wiring the LEDs, I added the buzzer in parallel with them
I had a problem with being able to use all of the breadboard, I guess I didn't completely understand how the breadboard works, So I got back to the recordings and asked my peer YASSIN who kindly explained to me how to connect them together and he sent an awesome link which solved my problem
I understood more about circuits as it was my first time dealing with electronics. So I guess it will help with my final project to wire resistors with different values with LEDs to help with understanding if the kid is using the right part of the game or Not.
final project
It was my first time to deal with electronics and it felt wonderful to be able to make a lot of hands on activities with alit of trail and error.
I made a race car with my friend Eslam. And it was great that both of us have no background in electronics and we managed to make a functional and stable car. Not just that we came in the first place when competed with other teams. It felt great to be able to make something you never thought you could do. This activity made me believe in myself and that I'm capable of anything If I put the proper time and effort into it. Thanks to Maker Diploma I believe I can do anything rn.
