Hi everyone An update/more questions
Yep I got Arduino talking to ChucK now with the* ints.ck <http://ints.ck> *script in the Serial folder under examples (don’t know why it wasn’t there so I just downloaded source/help files again!). Although I cant seem get *seiralRecvArduino_3.ck* to receive any data from my Arduino. Is there a way of modifying* ints.ck <http://ints.ck> *to receive /parse the incoming values from my x4 potentiometer? Thanks for any explanations/advice-much appreciated! Alan My Arduino code is below // the setup routine runs once when you press reset: void setup() { // initialize serial communication at 9600 bits per second: Serial.begin(9600); } // the loop routine runs over and over again forever: void loop() { // read the input on analog pin 0 to 4: int sensorValue0 = analogRead(A0); int sensorValue1 = analogRead(A1); int sensorValue2 = analogRead(A2); int sensorValue3 = analogRead(A3); int sensorValue4 = analogRead(A4); // print out the value you read: Serial.println(sensorValue0); Serial.println(sensorValue1); Serial.println(sensorValue2); Serial.println(sensorValue3); Serial.println(sensorValue4); delay(1); // delay in between reads for stability } On Fri, Jan 3, 2014 at 4:19 AM, Steve Morris <[email protected]> wrote: > In case anyone is interested Firmata is two things. 1) It is a piece of > software that runs on Arduino that allows sensors to be read via a serial > port protocol. 2) The serial protocol is also called Firmata or the Firmata > protocol.
