You can use the DC Barrel connector to power with 12v

 

What voltage is suggested for this? Also is there a way to add an led to this so it goes on when it switches to pump gas?

 

Finishing up a smaller version of the E85 setup with a Arduino nano,, more compact

 

so i bought this board https://www.adafruit.com/products/1447 because i happen to be on the site buying the arduino...wondering if its still the correct board?

also, is the code on the first page still not set up for the 16x2? could i bother you for the 16x2 code if possible? Thanks!

 

That one is fine. Just more wiring.. I bought a lcd with the dimmer modulator all ready installed. And only use 4 wires.
And u can use the Arduino clones. Work the same.just way chaeper.. here is what I use..
Stainsmart 1602 with the lcd dimmer in.built in.
And a arduino clome Elegoo uno r3
And yes the code is still for the 16x2 lcd

 

O ya and if u want a much compact setup. Use the Arduino Nano.. and yes they do makes clones.. And they are under $10

 

Yeah having some issues still, but will play with it more

 

Hey mrb00st Do u know how to re-write the code for a oled 0.96 or 1.3,
Thanks.

 

This is what i was looking for, nice write up. also has anyone done a gauge like this one

 

IM BACK! lol sorry for the hiatus. Took a new job and havent had a lick of spare time. I recently updated the library, some users were having issues with getting it to work. So i added 2 folders and u just drag and drop.

 

I have not yet gotten my hands on a oled screen. If you have one, shoot me over a pm and i can send u the code i have to test.

 

Hey so I uploaded the code onto my arduino but when I wired up the lcd I am getting nothing. It does boot up and the screen lights up but no info is being displayed however my laptop shows that the loop is running and there is info being captured (0% eth. I think). We added the libraries from the folder linked in post #1. Any idea on the problem? Maybe I'm missing a proper library? Thanks for the help in advanced!

 

normally when this happens, your SDA and SCL wires are backwards OR the POT on the back of the screen needs adjusted

 

Hmmm I adjusted the POT but I will triple check the wiring. Thanks!

 

If they doesnt work, u will need to check your I2C address. Using this here. This will spit out what the address of your I2C is so you can adjust it correctly in the code for the sensor
