ITender communication with the real world
As announced in the old tickets, I set up two systems with node-red.
1. iTender writes!
This is an opportunity to use Sense Hat! my goal is:
- display the temperature of the cold liquid
- to mark the name of the cocktail during its preparation
For that on node-red there is node which makes it possible to communicate with Sense Hat: node-red-node-pi-sense-hat.
Here is the procedure I followed to make it work :
1.1 Sense Hat wiring
I'm starting to have many GPIOs to use, not to use the same GPIO for 2 different functions I have in place a plan for using raspberry pine. For this I looked for a plan that shows the use of GPIO for the "Sense H at". Here it is
http://mshaughs.blogspot.fr/2017/02/sense-hat-pinout-for-raspberry-pi.html
Sense HAT | 1 | 2 | Sense HAT |
3 | 4 | 5V | |
Sense HAT | 5 | 6 | Sense HAT |
DS18B20 | 7 | 8 | Cold circuit circulator |
GND | 9 | 10 | Peltier 4 |
Pump 1 Pineapple juice | 11 | 12 | Pump 2 Orange juice |
13 | 14 | GND | |
Pump 3 Coca | 15 | 16 | Sense HAT |
3,3V | 17 | 18 | Sense HAT |
Peltier 1 | 19 | 20 | GND |
Pump starts cold circuit | 21 | 22 | Sense HAT |
Peltier 2 | 23 | 24 | Sense HAT |
GND | 25 | 26 | Peltier 3 |
Sense HAT | 27 | 28 | Sense HAT |
29 | 30 | ||
Pump 4 Cane syrup | 31 | 32 | Pump 5 Whisky |
33 | 34 | GND | |
Hot circuit circulator | 35 | 36 | Pompe 6 Wodka |
Pompe 7 Rhum | 37 | 38 | Pump starts hot circuit |
GND | 39 | 40 | Pompe 8 Perrier |
1.2 Installing node-red-node-pi-sense-hat

1.2. Display the temperature on the LED matrix
For that I realized the following program :

2. iTender speaks!
And today iTender speaks! A touch of fun in this crazy project!
For that I use "node-red-node-watson":
https://flows.nodered.org/node/node-red-node-watson.
I use more specifically the node "text-to-speech" for the configuration I invite you to watch this video :
I also use "node-red-contrib-play-audio" : https://flows.nodered.org/node/node-red-contrib-play-audio.
Here is the program that announces the name of the drink when I throw a cocktail.
