A buddy that reminds you to get off your phone and actually code! It was a 2 day (weekend chalenge) I did to test and apply my knowledge. It was fun and painfull.

I made a desk buddy that has simulated emotions. It can get angry curious, happy,bored and is somewhat of a nerd.It helps you code better as it is based on the talk to the rubber duck theory wher a passive listener helps you structure your thought. It s name is Axel. It is scared of the dark. It was a chalenging and rewarding process!It realy just started off as a chalenge between myself and I.Iw is costructed of:
HC-SRO4 Ultrasonic Sensor
Speaker/piezo
Servo 180 motor
LCD screen
Light Dependent Resistor
10kΩ potentiometer (for the lcd screen, you can just use an I2C)
Rgb ring (for a visual effect)
Breadboard Power Suply for more flexibility
2x9v batteries
It has many outputs! And multiple ways of interaction.The video has only some of them so I suggest you take a look at my code and readme from github! I am very proud of this little project. I believe you ll like it too.

I finally coded it and it works I still have to make some last minute changes and it will be ready to ship!!!

So I officialy finished the hardware.I added a PIR sensor and an Ultrasonic sound sensor.I mapped all the pins and made a list of the components I used Arduino Uno R3
16x2 LCD Display HD44780
10k potentiometer
PIR Motion Sensor HC-SR501
Ultrasonic Sensor HC-SR04
SG90 Micro Servo Motor
Passive Piezo Buzzer
breadboard
jumper wires
220 ohm resistor
1000 ohm resistor
external 5V power supply…
Now I think I am ready for the code (I am NOT READY for this emotional roller coaster)I tested all the components so if anything goes wrpng I ’ll be sure it is a software problem. Also the Assistant might look cheap and too low quality. But it is all I can currently afford. Maybe, maybe if stardance gives me a 3d Printer all my projects will be professional (just kidding(not rly)).See you in the next dev log.

So I got the Lcd working!I am off to the other components now!!!

I am having a big trouble with coding. I took apart the assistant to do everything 1 by 1.

SO scraped the whole project and re started from scratch.I added an Lcd screen (didn’t have I2c). Added a tap sensor,a servo motor and a PIR sensor. Also I boversoldered the other speaker and now it doesn’t work so I used a smaller one with two capacitors to smooth out the sound and it is preety neat.Now to the coding!

So I completed the physical built.I didnt use an LCD cause I dont have I2c one but there will be voice and sound feedback from the companion.While I might change anything I can in the future.Next dev log will be me writing the code and finding out how to wire some parts I never used before.

I finished a big part of the cardboard mvp everything is cut out.Next devlog will feature a photo of the MVP

I added the basic components and decided I will make an MVP out of cardboard an I ll ship it that way.It will all run on an arduino uno.It is preety neat I ll post pictures from next devlog.Stay tuned!

So I started on the research of what to do and searched for what i had available.I’ll prob have to buy an i2c lcd screen cause mine is broken. I added a servo and an ultrasonic sensor to the hardware.I am also thinking of putting a tap module.I only have a buzzer i think for sound feedback
