I sketch the standard-firmata on my Arduino and after make blink node based on example I faced with this error: "TypeError: Cannot read property 'on' of null"
Which example? Please export the part of your flow that shows the problem and paste it here.
this arduino blink example
in debug this is error: TypeError: Cannot read property 'on' of null
and in cmd :[error] [arduino out:47fa459b.750dfc] TypeError: Cannot read property 'board' of null
[arduino out:47fa459b.750dfc] TypeError: Cannot read property 'board' of null
I think I should add device name but I dont know how. this is wemos D1 R2
1- have you flashed standard firmdata on the arduino board and connected through USB?
2- Have you defined the proper port of your arduino board on the node red arduino node?
yes a flashed standard firmdata and also select com4 in arduino node
Are u under windows?
I tried both windows and linux
I'm using raspbian and frankly speaking I don't know exactly what your problem is because the steps are really simple:
1- install arduino node on node red.
2- flash standard firmdata on arduino board and plug to USB
3- define your usb port on some arduino node
And directly works, I have being never able to use jhonny-five and I don't know why but directly use the arduino board as simple in/out is very easy.
Re-check the steps I told you....
