00:01Hello, test successful. Yeah, I can hear you. Test is successful.
00:06We have a 4-ohm speaker, which is connected to the SP plus and SP minus pins on the board.
00:11This is an automatic GSM calling device that we built using this Geolinger GL868 development board.
00:17Let me show you how it works.
00:19So we have our device over here and our person is standing over there.
00:23Now I'm going to show you a live demonstration. Let me give him a call.
00:31Yeah, it's ringing.
00:38Hello, test successful. Yeah, I can hear you. Test is successful. Thank you.
00:43Okay, nice.
00:45The connections are so easy. We have a 4-ohm speaker, which is connected to the SP plus and SP
00:50minus pins on the board.
00:51We have a normal condenser mic that's connected to the M plus and M minus pins on the board.
00:56Then we have this push button, which is connected to the GPI of 4, which is on the board.
01:01Then we have a 3.7-watt lithium battery that's connected to the battery tunnel on the back side of
01:05the board.
01:05That's it about the connection.
01:07This project becomes helpful for elderly people as they can simply press a button and call their family member or
01:13an emergency service.
01:14The full project details is provided in the description.
01:16Thanks for watching. Bye.
