  • DS18B20 (digital temperature sensor) and Arduino 8 days ago

    Hello, I try to test this example project (read a 18B20 temp sensor). but I can't compile the code. I always get this error:

    "U:\Documents divers\Arduino\mes_programmes\DS18B20_test\DS18B20_test.ino:1:21: fatal error: OneWire.h: No such file or directory #include <OneWire.h>"

    I downloaded OneWire.h file from this web site and saved it in the same folder with the program itself (.ino file).

    What is wrong?
    Thank you for your help.

    Hi Frank, try to disconnect your microphone from the Arduino, and key the PTT (simulate the PTT) by shorting pin A3 to ground. When you disconnect the wire, the transmitter should keep on transmitting for 1 second (transmitting the "beeps") and then turn off. If this works this means there is a problem with your microphone (possibly a bad connection). Good luck.

    Note: The Arduino power supply must be between 7 VDC & 14 VDC.
