I bought one of these sensors a week ago and struggling to get it working properly. The code they provided did not work.
Ive managed to get a reading through the serial, digital 0, 1 pins and then entering this code:
void setup() {}
void loop(){}
opening the serial reader and entering "C" to start taking a reading at 620ms. you should get something like this.
14,8,414,14,1410,10,1413,18,18
What I would like to know is how can you use soft serial and strings to be able to take a reading that arduino can then do something with.
