This is what I did to power the Arduino which I used in my engine start button project. It’s a simple and cheap way to power an Arduino in a car. This will requires some basic soldering skills.
But a simple USB charger – the kind that plugs into your car’s power outlet. They usually cost ~$2-5(USD). You can probably find them at most convenience stores, or maybe a box store of your choice.

I recently purchased a 4 channel relay module and a start button from a Mazda 3. The relay module cost me $8.49(USD) from Sain Store on Amazon.com. The Mazda 3 start button cost $25.00 off ebay.
I wrote a program for the Arduino, and put together a test circuit to see if it would work. I used LEDs to show the functions. I wrote 6 different versions of the code until I finally came up with one that worked exactly how I wanted. I’m not a programmer, so this code is […]
I recently test drove a ’14 Honda Civic, and I really liked some of the new features that Honda has added to their vehicles. The start button intrigued me. It used to be that the S2000 was the only vehicle that Honda decided to have an engine start button on, but now it seems that […]
Is your check engine light(CEL) on? Getting the trouble codes from the Engine Control Unit(ECU) might make it easier to fix the problem. Here is how to get the trouble codes. The ECU is located at the front of the passenger foot-well, under the carpet. There is a single flashing LED(Light Emitting Diode) at the center […]
