Problem on Gathering Ultrasonic Sensor Data Through Firefly

Hello,

I have been trying to get the data using the code Firefly_Firmata_ping.ino uploaded by another user however in Grasshopper, I can not obtain any useful data from the uno read component.

As the sensor is plugged into Digital Pin 2 as instructed, the distance is supposed to be seen when a panel is linked to DPin2 on UnoRead component but it just writes "1" whena panel is plugged in. What is it that I am doing wrong?

Thanks!

I also can not obtain useful data using these instructions, using regular Firefly_Firmata code.

Hi Cemre K, I realise this will come too late for you but I will put it here for anyone else having trouble. I have a tutorial and video showing the process of reading an ultrasonic sensor using the stock Firefly firmata via 'serial read'. http://troybaverstock.com/learn/firefly-serial-read-ultrasonic/
