My first project is getting close to being finished and for the next project I want to build a communication device within our house, preferably ‘powered by blynk’.
The problem is that we have 4 floors and a teenager with headphones playing fortnite on the 4th floor, getting his attention is a pain and when we have it its still a pain to communicate.
The ideal situation:
- have a ‘box’ in his room that grabs his attention with a loud ‘beep’ and then allows 2 way voice communication
- communicate with that ‘box’ in two ways:
a. with phone through the blynk app
b. with another box on the ground floor.
(in case people suggest giving him a phone: he already has one and its usual state is either:
Now I’m aware that voice communication with blynk is not possible, best option is using the streaming widget and set something up through the server. Let me say though that it would be a nice feature if sound can be transmitted with the blynk app (e.g. for a door intercom).
Hence the question is: how to build this in Blynk?
Online, the best I could find was:
which is a rather crappy solution and moreover doesn’t involve blynk, nor a phone.
Obviously I have give this some thought as well and so far the best I could think of:
- ‘the box’ consists out of an ESP8266, a speaker, an amplifier, a button and an LCD screen.
- the blynk app consists out of a text entry field and a button.
from the app you can enter text (or select some ‘default’ texts) and hit a ‘send’ button.
Then on the box a beep sounds every 5s until the button is hit and on the LCD the message is displayed.
When ‘the button’ is hit, the app shows a ‘received’ message.
I’m however open to suggestions to do this better or differently or easier or if you just have a cool thought…please let me know.
