Code

The code in the editor below is ready to run! Plug Code Lab Mini in to your computer's USB port, make sure that your Code Lab Mini Sensor Trio Add-On (sold separately) is attached, and hit 'Upload Your Code!' to see what it does. Change something in the code, like a delay or pin number. Try to add something new to the program - it's yours to tinker with! You can always press the 'Restore' button to return the code to the working example.

If you haven't set up your Code Lab Mini Sensor Trio Add-On yet, visit Chapter 0 to watch a video showing you how to do that.


/* Turn on an LED light when the sound trigger 'hears' a sound. This program requires the Sensor Trio add-on to Code Lab Mini, sold separately from the Code Lab Mini You can change the threshold where the light turns on by changing the number in the 'if' statement The sound trigger has a range of 0-1023. Lightly tap it to see if it's working */ void setup(){ pinMode(A3,INPUT); //sound trigger in the Sensor Trio add-on pinMode(8,OUTPUT); //LED light } void loop(){ if(analogRead(A3) > 700){ //if the sound level spikes above the threshold of 700 digitalWrite(8,HIGH); //turn on LED 8 } else{ //otherwise if the sound is lower than the threshold you set digitalWrite(8,LOW); //turn off LED 8 } } // (c) 2023 Let's Start Coding.
