i wanted a garage door opener i can use from my phone. i also am teaching my self programing and cad so this was perfect. i found a post on makezine.com (https://makezine.com/projects/particle-core-garage-door-opener/) “open your garage door with a smart phone and particle core” it is a few years old but it seemed like it should still work for what i wanted i also had everything needed except the particle core so it was perfect being new to this when i went to amazon i found the particle photon and i ordered it by mistake luckily i found out its pretty much the same thing Things you will need for the project: to start print this box i made out! here is the project list. these were not bought specifically for this project there these are all things i had purchased for other products and work for this project. all of these were purchased off amazon at one time or another. <a href="https://www.amazon.com/dp/B016Q6T7Q4/ref=cm_sw_em_r_mt_dp_U_HgDXCbGB4SBZ0"> mini breadboard</a> <a href="https://www.amazon.com/gp/product/B07GD2BWPY/ref=ppx_yo_dt_b_asin_image_o01_s00?ie=UTF8&psc=1">jumper wires </a> <a href="https://www.amazon.com/gp/product/B016YNU1A0/ref=ppx_yo_dt_b_asin_image_o06_s00?ie=UTF8&psc=1">particle photon </a> <a href="https://www.amazon.com/gp/product/B00XAGT2OG/ref=ppx_yo_dt_b_asin_image_o08_s00?ie=UTF8&psc=1"> 2 channel 5v relay </a> to close the box i used 2 - m3x8mm screws, it does not require nuts just the screws i have this <a href="https://www.amazon.com/gp/product/B014ONCP88/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1"> Assorted M3 screws with nuts</a> kit and it is mounted to the garage door opener with random velcro i had laying around. its not heavy so any velcro should do or you could use 3m stickies. its powered by an old samsung charger and usb cable plugged into the photon. the relay jumper is made out of 22 awg braided wire and the cables connecting the relay to the garage door is the same 22 awg braided wire with some quick connect end fittings from <a href="https://www.amazon.com/Glarks-Disconnect-Electrical-Solderless-Connectors/dp/B01E4RAVI0/ref=sr_1_9?crid=MYF5QJX7O9V7&keywords=cable+connector&qid=1557682498&s=gateway&sprefix=cable+con%2Caps%2C160&sr=8-9">this kit</a> you will also need the blynk app on your cellphone and a particle.io account. (it was noted that if you are worried about security of a cloud based service.. you can have your own blynk server!) Setting up the blink app: once you log in you will need to create a new project and name it and also select the particle photon from the drop list. its going to give you an auth token so you can access the blynk app, have it email it to you so you don’t need to remember it and hit the button the create the project, touch the screen to open the widget box and click on “button” after that make sure where it says pin you change it to say D0. hit ok and your good with the blynk app next step were going to use the particle IDE. create a new project and name it. this is the code i used.. you will see it says “ENTER YOUR AUTH CODE” fire up your email and get that code you sent your self earlier and past it in there between the “ “ copy between the code i used can be found here: https://pastebin.com/qWsUd0xi my wiring from the photon to the relay goes red = GND to GND orange = IN1 to D0 yellow = IN2 to D3 green = VCC to VIN wiring on the relay and to garage door opener: you need to put a jumper from com1 to com2 (common 1 and common 2) and the wires that go to the opener connect to NO2 and NC1 (normally open 2 and normally closed 1) Connecting to garage door opener from relay: garage doors are as similar as they are different, if you only have two wires on the back of yours they are the ones you want to connect the NO2 and NC1 wires from the relay to.
