Hi. I am working on a project where you can send an SMS to the sim900 in a greenhouse to get the temperature from a DS18B20 sensor and control other variables and see other data.
Nice. Please describe the problem in the post, not just the thread title.
Look at the StateChangeDetection example sketch for a solution.
Hi, this isn't my full post. I accidentally clicked post (oops!). However, i now posted my full question if you could help at all.
Please edit your first post to include the code, using code tags, and explain the problem.
After, of course, carefully reading the instructions in the "How to use this forum" post.
Feel free to delete your second post.
