I have to work on each bit separately. i am not sure about Serial.read() gets it as binary but when i am trying to see at on the serial port screen with Serial.println(Serial.read(), BIN) it shows me as string something like []...[] What should i do ?

  • A byte is 8 bits. You can use "bit manipulation" to extract or set single bits. A very good tutorial here: (avrfreaks.net/forum/…) Commented Jan 19, 2017 at 11:33

    There is a difference between binary form and base 2 (BIN) number conversion. Commented Jan 19, 2017 at 12:09
  • Serial.read() reads a byte (8 bits) so you should receive 8 bits at a time. If there is some form of flow control then you might just get 1 bit. It looks like you are not getting any bits so check your code is waiting until data is available. Commented Jan 19, 2017 at 13:03
