week 6

Ideation

Tell us about your assignment's idea for this week. Why do you care about this idea? What inspired you?

The assignment was to build and Program a smart circuit using an Arduino UNO which reads a signal from an input component SO I decided to build a circuit of dc motor that changes its direction when there is movement in front of an ultrasonic sensor

Tool Chain

Which software/machines/materials did you use in the assignment? Why?

For simulation

I used tinkercad to simulate the circuit

For actual circuit

I used

bread board

dc motor

5v adaptor

Ultrasonic sensor

arduino

h bridge L -298N

SWITCH

2 led lamps

crocodile wires

For uploading the code to arduino

arduino ide soft ware

Design/Preparation Process

I started by simulating the circuit on tinker cad that at first I connected the5V bin and the ground of the arduino with the bread board

then connected the vcc and the ground of the ultra sonic sensor to the ground and the 5v of the arduino and connected the trigger with pin 10 and the echo with pin 11
also connected the dc motor and the power supply with l293d and connected the enable with bin 9 and connected the inputs with 3/5 pins and also connected it with the ground and the 5v of the arduino
also connected the switch with the ground and 5v and bin 2 of the arduino
also connected red and blue ledwith the ground and bins 13 /12 of the arduino

code blocks

I programmed the circit that when I move the switch the circuit will work and the dc motor will work in one direction and the blue lamb will wor when I put my hand neer to the ultrasonic sensor

the motor will change its direction and the blue lamb turns of then the red lamb will work

Development/Implementation Process

Explain the development/implementation process of your assignment. How did you use the machine/tool to manufacture or implement the design of your assignment?

I made the circuit outside like it was on tinker cad that i connected the components with the arduino and the breadboard together then copied the code from tinker cad and pasted it on arduino ide then I uploaded it to the arduino board I connected the dc motor with L -298N that is connected with adaptor 5v when I uploaded the cod i opened the circuit with the switch and the circuit worked correctly

Community of Learning

Did you ask for feedback? What are the ideas that others have contributed or suggested? What was someone else’s idea that you built upon? How did you help your peers? How did your peers help you?

at first i asked the instructors if the idea of the assignment meets the requirements also i asked if it was possible to be made

also I faced a problem that the arduino didn't accept the code that when I press upload the code is not installed to the board and it gives me error massage so I asked the instructors and my peers on slack they tried with me a lot and gave me advices after following their advices and searching a lot f finally it worked after I installed drivers from boards manager on arduino ide i could uploadthe code on the arduino

also i couldn't use the ultra sonic in a right way but during this activity with my teammates i figured out how to connect the sensor in aright way and how it works

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 assignment?

In the simulation of the circuit in tinker cad the motor wasn't working In right way it was lagging and doesn't work in one direction but when i rearranged the blocks and put the blocks of the motor firs it worked will
