It's a kit that teaches kids about shapes.I searched for it on Google and found it, but the virgin I found was saying the name of the shape, in my prototype when the proper shape fit the empaty space, the buzzer made a sound and the bulb lit up. the aim of the kit is to help kids from 3 to 5 years to know about shapes when the right shape insert to the right place a led lights and the buzzer make sound.
Before I applied the circuit physically, I used Tinkercad to simulate the circuit and acquire recommendations. used tinkercad
the materials
breadbord
buzzer
Red led
resistor
push-button
crocodile
9 v adapter
male-male wire
on-off switch
potentiometer
cardboard
glue gun
tape
First and foremost, my concept necessitates the simultaneous operation of a buzzer and a led, requiring the circuit to be connected in parallel. It also necessitates the use of a bush button, which will be connected in series.
Then I started simulating the circuit in Tinkercad by connecting it in parallel and the push button in series.
after that prototyped the circuit on breadboard and troubleshooted it
Dc motor 9 v, resistant 220 ohm ,piezoelectric buzzer is recommended to be above 9V to obtain a larger sound,A red LED typically drops around 1.7 to 2.0 volts
The final stage was to create a cardboard body.
the circuit connection is parallel between all parts except the on\off switch its series.
I simulated the kit in Tankercad, then went to the toolbox to look for the component I required and googled voltages before starting to build components in a breadboard. After finishing the circuit and troubleshooting it, I moved on to designing the kit's body. all the circuit connection s are parallel except the on-off switch is series
I told Abdelrahman and Mahmoud about my idea, and they told me about various changes I could make to the shape of the design, as well as how to move the pushbutton to make the function work better.
The led did not light during the process, and I was confident that I had connected the circuit correctly, so I used the potentiometer and discovered that one of the male male wires was not working.
I faced a difficulty with the push button not working and asked for help, only to discover that I had connected it in parallel rather than series.
Developing the final project idea and implementations will be greatly aided by creating an electric circuit.
