Esp8266 / Nodemcu Texting Doorbell

thingiverse

This is just a project for a texting doorbell that I scratched together after a bit. I had an existing wireless doorbell so I took the existing outside electronics and put them in a box along with a esp8266 and a relay. The button outside tells the Node to send an Email and also activates the relay. The output of the relay goes to the button that was on the wireless doorbell board to make my recievers ding. I then have my Gmail account setup to forward the incoming email to my phone as a text. I have updated the button outside to a regular doorbell button and added a led behind it to light it up. I also added in the code to make the led blink a couple times when the button is pressed so the person outside can see that it worked. For the esp8266 setup I used this video. www.youtube.com/watch?v=znFMNzT_Gms After going through the video I modified the code to watch for a state change and then execute the web request. You can also make this send some data through the value portions of the code if you wanted to. I am not a coding expert in any way and just know the basics pretty much. I will post my code in a text file with most of the instructions out to the side. Although I would watch that video first. If I missed anything important let me know. Things used These are the buttons I used but I think im going to swap mine out for regular doorbell buttons: https://www.amazon.com/Cylewet-Momentary-Button-Switch-CYT1078/dp/B0752RMB7Q/ref=sr_1_1?keywords=cyt1078&qid=1555465133&s=gateway&sr=8-1 Regular doorbell button I swapped to: https://www.amazon.com/Heath-Zenith-SL-664-02-Button-Finish/dp/B000BQPI8M/ref=sr_1_4?keywords=doorbell+button&qid=1556240905&s=gateway&sr=8-4 Led I added to the doorbell: https://www.banggood.com/100PCS-2x3x4mm-Wide-Angle-Flat-Top-LED-Diodes-Water-Clear-Transparent-Light-Lamp-p-1075736.html?rmmds=search&ID=233&cur_warehouse=CN Amazon link to led's: https://www.amazon.com/Rectangle-Transparent-Lighting-Electronics-Components/dp/B01C5HL0PO/ref=sr_1_1?crid=11JF98RKW32TS&keywords=2x3x4+led&qid=1556241074&s=gateway&sprefix=2x3x4%2Caps%2C283&sr=8-1 Nodemcu: https://www.amazon.com/HiLetgo-Internet-Development-Wireless-Micropython/dp/B010N1SPRK/ref=sr_1_1_sspa?crid=2I2N5KEF0Q60T&keywords=nodemcu&qid=1555466067&s=gateway&sprefix=node%2Caps%2C170&sr=8-1-spons&psc=1 Relay: I used these but they are 5volt relays. The node operates on 3.3 volts so technically you should use the ones in the second link I put. But the 5volt ones do function on 3 volts. 5volt: https://www.amazon.com/HiLetgo-Channel-optocoupler-Support-Trigger/dp/B00LW15A4W/ref=sr_1_3?keywords=5v+relay&qid=1555466099&s=gateway&sr=8-3 3volt: https://www.amazon.com/Channel-Driver-Module-Optocoupler-ESP8266/dp/B0798CZDR9/ref=sr_1_1_sspa?keywords=3.3v+relay&qid=1555466133&s=gateway&sr=8-1-spons&psc=1
