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 directions in front of LDR and IR sensor

Inspired by cubetto

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

arduino

h bridge L -298N

SWITCH

2 led lamps

crocodile wires

ldr sensor

IR sensor

lCD

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 breadboard

then connected the Vcc and the ground of the sensors to the Arduino
also connected the dc motors and the power supply with l293d and connected the enable with bin and connected the inputs with pins and also connected it with the ground and the 5v of the Arduino
also connected the slide switch with the ground and 5v and bin 2 of the Arduino
also connected red led with the ground and bin 4 of the Arduino

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 assembled the components together in a cardboard

Then I wrote the code on Arduino UNO to move to forward when I cover the LDR sensor and move to back when I cover the IR sensor and when I cover both sensors it will move to the front then to back

the code

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?

the code didn't work and I couldn't figure out what the problem was so asked on slack and I found out that I wrote digitalWrite instead of digital read.

also, I had a lot of troubleshoots with the code and the instructor helped me to solve it.

we learned how to make a smart home simulation in the EO week session by using a DHT sensor

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?

At first, the code didn't work so I rebuilt the circuit and rewrote the code several times until it worked well

also, the Arduino didn't work well I searched for the problem I found out that the switch was making a short circuit so the Arduino didn't work so I used a slide-switch instead of it to solve the problem

Final Project

How can you use the skills and knowledge that you've acquired this week in your final project?

WOW now I can say that I can code the final project the I have imagination about how 70% of the code will be

WOW!

What is the coolest thing that you've learned this week? What is something that you will never forget from this week?

MY Assignment

during the week I was learning how to write Arduino codes an the process wasn't easy I had a lot of pugs but finally, the code worked and the project worked as I imagined and it was cool

Weekly Digest

Tell us about any other cool things that you've made this week: in the Hands-on activity, tutorial examples, exercises, or any other cool mini-project that you tried out aside from the assignment.

I made a Cooling system using DHT sensor with the help of my teammates
