SMS to light an LED!/products/arduino/arduino-tutorials/b/blog/posts/sms-to-light-an-ledHiI have been playing with my Uno and GSM shield to try to see if I can get the real world to react to a good old fashioned SMS text. In these days of 3G and 4G data rates, I wanted to show that we don&#39;t have to have the latest toys to interact with en-USTelligent Community 12RE: SMS to light an LED!https://community.element14.com/products/arduino/arduino-tutorials/b/blog/posts/sms-to-light-an-ledWed, 13 Apr 2016 11:47:16 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:1dbacee0-84e2-431d-baad-d28b4d71f43eFormer Member0<p>Hi Markvenn, I have tried your code using a different setup. I used a SIM800L based GSM board with Arduino duemilanove.It worked as expected, if pins 2 and 3 are maintained as the serial communication lines. The problem is if you send an sms text other than red, green, blue, the setup hangs ie subsequent sms with red, green or blue will not work anymore until power is switched off and on.</p><p>I want to find out if you experienced that and what could be the possible solution. Thanks</p><p>&nbsp;</p><p>Kobby</p><img src="https://community.element14.com/aggbug?PostID=20405&AppID=148&AppType=Weblog&ContentType=0" width="1" height="1">RE: SMS to light an LED!https://community.element14.com/products/arduino/arduino-tutorials/b/blog/posts/sms-to-light-an-ledWed, 08 Apr 2015 15:04:10 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:1dbacee0-84e2-431d-baad-d28b4d71f43eneilk0<p><span>[mention:0aba3edcad8f4f68b7c24703bf23f26c:e9ed411860ed4f2ba0265705b8793d05]</span> - Mark, thanks for that; very useful. I&#39;ve often wondered what could be done with an SMS shield and now I have a nice example that can easily be developed. Thanks again</p><p>&nbsp;</p><p>Neil</p><img src="https://community.element14.com/aggbug?PostID=20405&AppID=148&AppType=Weblog&ContentType=0" width="1" height="1">RE: SMS to light an LED!https://community.element14.com/products/arduino/arduino-tutorials/b/blog/posts/sms-to-light-an-ledWed, 08 Apr 2015 07:04:34 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:1dbacee0-84e2-431d-baad-d28b4d71f43emarkvenn0<p>I forgot to put in the resistors on the fritzing breadboard :-(</p><p><span>[View:/resized-image/__size/620x438/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-1dbacee0-84e2-431d-baad-d28b4d71f43e/2860.contentimage_5F00_184273.jpg:620:438]</span></p><img src="https://community.element14.com/aggbug?PostID=20405&AppID=148&AppType=Weblog&ContentType=0" width="1" height="1">
