Buzzer
Ultrasonic Sensor
The Buzzer goes along well with the Ultrasonic Sensor. If you want to see the very basics of the Sensor, check it out.
Smart Security Alarm
After learning about the Buzzer, why not check out the Smart Security Alarm I made? You should probably check the Ultrasonic Sensor Case Study beforehand though. However, it's your life and your choices!

Code
The code below is my code so it's personalized but you are more than welcome to follow it. It's coded such that each key press on your keyboard is a specific note. I did this for a certain song I won't say here. Watch the video below to find out what song I designed this code for!
Here is also the code provided in the Junkbot manual for just a general music "keyboard."

Junkbot Core
(Arduino Board)
You'll need the the main board to do these case studies. It is based on the Arduino NANO. Check their site out for more details.
Sensors &
Components
You'll need many different sensors and components to put your board to use. Again, check their site out for more details.
A
Computer
You'll need a computer to program the codes that your board will perform along with the sensor and components attached. The programming tool made for the Junkbot Kit is also on their site.
