I don’t have any of those fancy pants remote controls for LED light strips so I made one with bynk…it’s a pretty impressive IOT app you can find here: http://www.blynk.cc
customize your interface by adding sliders/buttons/joysticks/etc
share your projects with anyone anywhete via the app and they can control your project from afar (perfect for putting your web-enabled cat feeder online)
Next project: once I have some more free time I’ll hack my roomba and then add it to blynk so I can schedule it from my phone while lying on the sofa eating bon bons.
Just bumping this as @Majicj were playing with Bynk this week. I forget to set the virtual pin in the Blynk app so beware - if your project doesn’t work with your lights but still connects over wifi it’s probably a virtual pin issue.
And…did some more investigation of bluetooth and Blynk. It’s doable but a bit unreliable (on byink anyway - for other purposes the HC-06 works great). Most people seem to use wifi with Blynk. I was exploring bluetooth because then I’d use an arduino with an HC-06 dongle.
I was thinking an arduino/hc-06 would be less likely to fry my USB port as the nodeMCU has no backwards power protection. Ah well - may have to haul out the USB isolater I bulit in one of @tomkeddie’s workshops.
All this came about because I was worrying about powering the Node/ESP with 5v through Vin and then accidentally powering it through USB also while programming it…thus cooking the port. I will just have to be careful.
edit: hc-06 is Bluetooth 2.1, Blynk does support BLE maybe that works better with teh new hotness)
