Tell us about your assignment's idea for this week. Why do you care about this idea? What inspired you? (Please include images or links to sources of inspiration
The assignment's idea for this week was about building and programming a smart circuit using an arduino UNO which reads a signal from an input component (ultrasonic-sensor) to control an action component (Buzzer) using code blocks.
at first i searched on Arduino project hub to find ideas but they didn't work with me (i started with difficult ideas ) ,so i decided to make a very simple model of my final project idea.
my final project is about making a third eye for blind that make sound from the buzzer when they get closer to any project.

searching for the datasheet of the Ultrasonic sensor which consists of four pins;
1-Vcc; The Vcc pin powers the sensor, typically with +5V
2-Trigger pin is an Input pin. This pin has to be kept high for 10us to initialize measurement by sending US wave.
3-Echo pin is an Output pin. This pin goes high for a period of time which will be equal to the time taken for the US wave to return back to the sensor.
4-Ground;This pin is connected to the Ground of the system.
Then connecting it to the arduino uno by the breadboard and wires;
-connecting the VCC to the positive ground which is connected to the power (5v) from the arduino uno.
-connecting TRIG to D3 of the arduino uno.
-connecting ECHO to D2 of the atduino uno.
-connecting the GND to the negative ground which is connected to the GND from the arduino uno.
searching for the datasheet of the buzzer which consists of two pins;
1-Positive;
Identified by (+) symbol or longer terminal lead. Can be powered by 6V DC
2-Negative;
Identified by short terminal lead. Typically connected to the ground of the circuit
Then connecting it to the arduino uno by the breadboard and wires;
-connecting the negative pin to the negative ground which is connected to the GND from the arduino uno.
-connecting the positive pin to D6 of the arduino uno.
using code blocks primarily to build my code on tinkercad.
-the ultrasonic-sensor is controlled through the input blocks(the purple block).
-comparing the distance through math blocks(green blocks).
-if objects get closer on distance equal or more than 25 cm, then the buzzer will make sound using trigger pin 3 and echo pin 2 to detect the distance as input and to send an output signal to the buzzer .
-if it was more tnan 25 cm in distance the buzzer won't make sound.
-the buzzer is controlled through the output blocks(blue blocks).

coping the code from tinkercad into arduino app so i can be able to connect it to the arduino uno through the cable.
connecting arduino uno to the laptop
then i made the same connection on the circuit

yes, i asked my friends for a feedback about the idea and they like it
i faced problems when i upload the code, i always had mistakes in my arduino code so my instructor advised me to arrange my ideas first as i should think before coding, it helped me in decreasing the mistakes.
i also faced a problem in making the servo motor with the potentiometer in the exercise of the end of week session ,at first, the way of thinking was to assign a rotation angle for every increase in the resistance of the potentiometer. Actually that wasn't the best way to do the coding as i would then get 180 if condition .
Overcoming challenges
Overcoming challenges
When you got stuck, what/who did you turn to? At what point did you have to pause to research or learn more before moving on? What are some mistakes, pitfalls, or challenges that others can avoid if they were doing this project?

i chose very cool ideas from arduino hub to make at first but i didn't know how to make the blocks of them.
