TouchDesigner to Arduino

This video follows up on the tutorial way back titled "Arduino to TouchDesigner (One-Way)" (   • Arduino to TouchDesigner (One-Way)  , which showed how to get sensor data from an Arduino board into your TouchDesigner network. This time I focus on the other direction, sending control data from TD over to an Arduino board in order to control LED's, motors, etc. See also a recent tutorial titled "Control 120V Electronics w TD + Relay Switch + Arduino" (   • Control 120V Electronics w TD + Relay...  .

00:00 PART 1: One LED On/Off
01:38 sendBytes()
03:30 Common error "avrdude"
05:00 PART 2: Two LED's On/Off
11:20 ASCII character encoding
16:20 PART 3: Two LED's & Two Sensors
20:07 PART 4: Move Servo w TouchDesigner
22:05 Audio input

Note: The eagle-eyed among you will notice that I also had a Part 5 featuring Servo, DC motor, and RGB LED which is not shown here. The code for that in TouchDesigner Chop Execute DAT and in Arduino is the same as in Part 2, except with a greater number of elements in the if/elseif chains... "A", "B", "C", "D", "E", etc.
