Garden Guardian

There are 4 main parts to the Garden Guardian: the car chassis, robotic arm,  LED Light, and the speaker. The car chassis and the robotic arm are being controlled by the Arduino.

Second Milestone

For my Second Milestone, I added Amazon’s voice control service, Alexa. I chose Alexa over Jasper because I have an Echo Dot and Alexa activated smart light bulbs at home.

First Milestone

My First Milestone for the Garden Guardian is to assemble the car chassis together and use code to make it move front and back.
