Installed Arduino IDE, and Added Sparkfun Apollo3 board support pack V1.1.2
Initially, the compilation was taking a very long time but after excluding the folder C:\Program
Files\Arduino from the antivirus scans, the compilation time reduced considerably
Running “Example: Blink it Up”:
Running “Example2_Serial”:
Running “Example4_analogRead.”: Grabbed the entire board inside my hand to increase the
temperature, and it took
a considerate amount of time for the temperature to rise
Running “Example1_MicrophoneOutput”:
As shown below, the yellow LED is turned on when the battery is connected. To program the board
so it turns
on when someone whistles, I used the general structure from "Example1_MicrophoneOutput" (6), and
I wrote in a
few lines of code, as shown below, to read the file, acquire the sensor readings, and put it
through a conditional statement
with some chosen threshold (1200). This value was chosen by experimenting, in general with
random noise the frequency is ~300 and
the whistling jumps it up to ~1400, therefore, a value of 1200 provides a safe comparison to
determine if the LED should
turn on or not. Finally, to turn on the LED, the code from "Example: Blink it up" (3) was
implemented.
