06 Mission Instructions

Your mission is to design a timer, with a loud alarm, and then send it wherever you need to keep track of time. 

7. Test

In this mission, you have two different things to test. Testing your program is pretty simple – set your timer to something short and then watch what happens. Does it match your plan? 

Testing your amplifier is a little trickier. Sure, you can listen to your buzzer with and without the amplifier you built, but can you be sure that it is louder with the amplifier?

If you want to make sure your amplifier is doing its job, you may want to test it in a more scientific way. If you have access to a smartphone or tablet, there are many free apps that measure sound in decibels. Try your buzzer with and without the amplifier and record the results on a piece of paper.
