First Milestone
My first milestone was making the real time ds3231 clock module work, it’s function is telling the time.I started off by placing the clock into a breadboard,connected the SDA and SCL pins on the Arduino to the clock, connected the GND AND 5V on the arduino plus the rails on the breadboard. I then continued by using javascript with the Arduino Editor to make the clock work.
Second Milestone
The second milestone was connecting two stepper motors to the project.The purpose of this was to make the stepper spin like the hour and minute hands of a clock.First i connected the negative and positive pins on the stepper motor to the negative and positive pins on the breadboard,IN1-4 pins to the digital pins on the Arduino.The steps and speed determined by the code made the motor spin every once every hour and minute.
Third and Final Milestone.
For the third Milestone i assembled all the components together on a wooden clock face.
Starter Project
The starter Project was connecting the servo to the arduino uno board. The purpose of this was to ensure the arduino worked,if it did the servo rotated fast or slow depending on how it was programmed.the first thing i did was connecting the servo arm and ensuring it stayed in place using a screw,then i connected jumper wires to the end wires so i could connect them to the arduino,i connected the brown pin on the servo to the GND of the arduino,the red pin of the servo to the 5V of the arduino and lastly the orange pin of the servo to the digital pin(9) on the arduino.My last step was programing the setup so it could function.Some issues i faced were trying to get the right code for the setup to work and where to connect the pins.
