Grasshopper
Firefly
Firefly offers a set of comprehensive software tools dedicated to bridging the gap between Grasshopper, (a free plug-in for Rhino) the Arduino microcontroller and other input/output devices. It allows near real-time data flow between the digital and physical worlds – enabling the possibility to explore virtual and physical prototypes with unprecedented fluidity.
How to control stepper motor in different ways?
Hi, I'm trying to understand how to use this Firefly. Firstly, I could have controlled servo motor with Firefly. Now, I'm trying to control stepper motor however I couldn't.
I use Arduino Nano and L293D. There is no problem in my circuit because it worked with Arduino IDE. I couldn't control it's with Firefly. I just can take a reading value but I cannot take a writing value. I will add my circuits photos.
What is my problem? Could you help me?

Hi! If you're using Firefly with an Arduino Nano and L293D, but only reading values—not writing—ensure your Firmata firmware supports stepper control. For enhanced signal integrity and safety, especially in noisy environments, integrating an isolation amplifier like the AD202KY can help. It provides galvanic isolation, reducing interference between your control system and motor driver.
