Using your voice to control everything has always been very interesting. With my shiny new echo I could connect all the usual "connected home" devices, but I really wanted the echo to keep my car warm and toasty on a winter morning. In this instructable we are going to make the Amazon Echo start any car. We will do this by programming a Raspberry pi zero to act like a Belkin Wemo switch, named My Car. You can then ask "Alexa turn ON my car"
1. Any remoter starter (compustar, drone mobile, Viper(viper has web APIs you can use :) )) + 1 extra remote (45$)
2. One 74HC4052 (~1$) (or use https://www.sparkfun.com/products/13906)
3. Pi-Zero (5$)
4. 10k resistor 1/4 W (https://www.sparkfun.com/products/11508)
5. USB OTG(https://www.sparkfun.com/products/11604) + Wifi Adapter(dongle) (15$)
6. pcb bare board (https://www.sparkfun.com/products/8808)
Open up the remote starter remote and disconnect the battery before you start. You could get away with connecting two wires on the opposite sides of the start button on your remote [shown in pic]. Every remote is wired differently, and you might have to figure out which two leads of the switch short when the start button is pressed. Also make sure you draw out the battery positive and battery negative(GND), this will power the 74HC4052 (Analog Mux). Now build the circuit shown in pic. This IC can support multiple buttons, but we are only using one channel right now. Make sure you short the enable pin to GND.
