In this tutorial, we show how to use LinkSprite caller ID module with Arduino. The chipset used on this module HT9032D. When someone is calling  (the calling telephone must not be private number), the caller ID module will output the caller ID through the  serial port (TTL level) in the format of  hexadecimal data. The packet includes date/time/phone number, etc.  The package will consist of bytes showing call coming, which shows ox55 for more than ten times, then followed by  ox04, after which will be bytes represent data length/date/time/phone number/BCC.[/vc_column_text][vc_tour][vc_tab title=”Items List” tab_id=”1422713031-1-25″][vc_column_text]

2. Then copy the test code to Arduino IDE, then download the code

3. If someone is calling, it will show the data,time and phone number, the effect will show below:
