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)

Step 1: Build your circuit

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.

<p>This is fantastic! My remote uses 3 key (lock) presses to launch the start sequence. What would be the easiest way to modify the GPIO command to have it fire the button command 3 times?</p>
<p>in your case you will need to use 3 gpios. </p><p>GPIO.output(REMOTE_GPIO1,GPIO.HIGH)</p><p>GPIO.output(REMOTE_GPIO2,GPIO.HIGH)</p><p>GPIO.output(REMOTE_GPIO3,GPIO.HIGH)</p><p>time.sleep(4)</p>
<p>I'm assuming you mean that I should have the gpio command run 3 times rather than using 3 separate GPIOs. <br>Here is where I placed it. </p><p><strong>def</strong><strong> changeIOState</strong>(state): <strong>##simulate long key press</strong></p><p><strong>if</strong> state:</p><p> GPIO.output(REMOTE_GPIO,GPIO.HIGH)</p><p> time.sleep(4)</p><p><strong>else</strong>:</p><p> GPIO.output(REMOTE_GPIO1,GPIO.HIGH)</p><p> GPIO.output(REMOTE_GPIO2,GPIO.HIGH)</p><p> GPIO.output(REMOTE_GPIO3,GPIO.HIGH) <strong>## check this if you two buttons to turn ON/OFF</strong></p><p> time.sleep(4)</p><p> GPIO.output(REMOTE_GPIO,GPIO.LOW)<br><br>I'm not seeing any continuity Between Y1 and Z when it runs. Did I place the code wrong, or is something wrong on the hardware side. </p>
Thank you so much!
<p>Hi, I just bought an Amazon Echo and want it to start my car. Can you please send me a list of exactly everything I would need to do this? My car is a 2015 Buick Encore.</p>
What are the names of the other parts you are working with? I see you used some blue cord, wire, and a round board. This is my first project and I am a little unfamiliar.
<p>the blue wiring, is described on step 1 (circuit diagram)</p>
<p>I have just updated step 1 with all required components.</p>
