Hello community,
I'm trying since weeks, to communicate with my arduino-uno with installed firmata-sketch via vb.net.
i've read mutch, but i'm stucking.
i bought a breadboard and established a easy-circuit. arduino-uno, resistor (220 ohm) and a led. after installing a simple sketch on arduino the led ist blinking as i want it to.
now i installed the firmata-sketch on my arduino and startet the test-application. i could easily controll the led via the windows dialog.
i tried to control my led with the example-firmata-project and vb.net 2010. the connect was successful. i activated the digital pin 12 (the one with the circuit on it), switched the mode to output and pushed the button to send the "high"-signal throught the digi-pin 12 - nothing happend. Only the onboard led indicated the serial communication between the vb-app and the arduino. the led does nothing. :~
when i switch to the pwm-mode the test-application crashes after a couple of seconds. then i have to unplug my arduino from power to reset.
does anyone have any sugestion? where could my problem be?
thanks for your help.
Greetings, Frank.
