Purchase

After seeing what an Arduino being used for my senior capstone project I got inspired to see what I could create with this technology. My first step was purchasing the Elegoo Uno Super Starter Kit

RGB LED

Using the guide in the Starter Kit I was able to light up a RGB LED, by changing its color from: Red to Green to Blue.

Ultrasonic sensor

This one was a easy to set up, once set up and coded it began to read values. All the values were within reason, there were a few outliers in the ~2200 cm range. After researching this sensor, it seems to be a common error. For the future all outlier values can be set to be ignored.

Temperature and Humidity

This sensor was easy to setup - VCC, GND, Output. While researching how to code this particular sensor I found two approaches. first to use the digital pins, second to use the analog pins. I tried both methods and found that the analog method was not reading. So I used the digital pin and the serial monitor can be seen above. I was also able to increase the temperature and humidity and the sensor displayed the new values.

Servo

Using the SG90 servo was easy to set up and use.
