Week 5: Active Buzzer

For this week, I chose to play with the active buzzer in my kit. I was looking for a project I had a little interest in and the active buzzer stood out to me because I have an alarm system that sets itself every night. Essentially, at 10 PM, my alarm arms itself and makes a variety of beeps at me. Simultaneously, my door lock beeps at me. So I'm thinking that the buzzer is kind of a variation on that. 

There were two types of buzzers in the kit - active and passive - I went with the active one, but I may check out the passive one too because apparently it can make different tones which is really what my alarms do. But the active one was easy to set up. I had to use another set of wire, Male to Female ones, which I didn't think I had, but realized they were all stuck together. I thought that was some huge super wire. I peeled two off and went for it. 

I used the provided code, but I was looking for what kind of variable would change and I found that in the speed of the beeps. When I changed that value, the beeps went faster or became more steady as you can see on the video. I didn't take many physical notes this time.
