![]() This procedure made my setup work with Joshua's Arduino sketch. Change the 'serial' object such that it now states 'serial 9600'. Make sure the main patch screen is locked (button next to freeze) and click 'Properties'ĩ. Next close the subpatch (properties) screen and unfreeze the Max patcher (lower left side of the screen)ħ. In my case the 'port b' showed the USB modem, which I guess is the port the Arduino is connected to.Ħ. All available serial ports should be printed in the console. In the properties section click on the red 'print' buttonĥ. From Ableton click on 'edit' button to launch Max editorĤ. I followed these steps to get it working (Ableton 10):ġ. I had the same issue described in the other comments. Thanks Joshua on getting me started for the ultrasonic controller! Then the new scaled values will control the “live.property value 1“ which will then update and control whichever parameter we have selected in Live Then the second two numbers are the new min and max values the input is scaled two which come from whichever device we have selected. The first two values are the min and max coming out of the Arduino, which you might remember from the Sketch (min 0, max 30). The scale object makes everything nice and neat. Those numbers are passed into a scale object. That data is read, interpreted and translated into numbers Max can work with. The print button will help to make sure you have the correct COM referenced.Įssentially what is happening with the additions is that we are telling Max to open a “serial connection”, info passing over USB, and look for any data being sent out. Now we need to add the following objects into the patch.Įverything that is red in the photo below is what we need to add in order to make this patch communicate correctly with the Arduino. int maximumRange = 30 // The max distance observed from the sensor.Then you need to change the input min/max on the “scale” object in the Max patch, more on that in a bit. So, if you want a longer or shorter range you need to update the values in the sketch and re-upload to the Arduino. These determine how far the sensor will be looking for movement. The only numbers you need to make a serious note of are the max & minimumRange values. Those numbers are the distance in Centimeters. Moving your hand closer should result in smaller numbers and farther away will get larger numbers. Then if you wave your hand in front of it you should see values. ![]() It’s the little magnifying glass icon in the top right of the program. When there is nothing in front of the sensor it should just be printing -1 after -1. We can also verify that the numbers are being printed correctly by opening the Arduino Software’s Serial Monitor. Remember there will be a slight delay, so don’t panic! You should see the LED on the Arduino turn off when your hand is in range. Once done you should see a message saying it was uploaded successfully. Now, we can verify that everything is working. This will read your code and make any changes to the formatting.Ĭlick the Check Mark in the top left to Verify the code. If you are good to go and have no errors, which should be the case if you did things correctly, hit the Right-Facing Arrow to upload the Sketch to the Arduino. It is at the top and it’s called “Auto Format” (Ctrl+T). Now, if you are like me, and you like your code to look beautiful, there is a neat option in the Tools menu.
