Arduino controller shield for coffee roaster

$250-750 USD

Closed
Posted almost 4 years ago

$250-750 USD

Paid on delivery
I've been working on this for a while, even paid someone recently, and I'm still not happy with the results. I have a coffee roaster with a proportion valve for the gas, and a digital gas meter that outputs a 4-20mA signal. What I'm looking for is to have a hand held module (which I've already 3D printed) with the following features: -LCD Display (installed) and currently reads Gas Pressure in kPa and Total Gas %. -LCD Display a scale on bottom of screen that displays on a scale between 0-5 what the current gas setting is. -Potentiometer or Rotary Encoder for controlling gas pressure (Proportion valve with driver) -As for hardware, I have a small PCB that converts the 4-20mA signal from the gas gauge to higher voltage for Arduino to read - This needs 9volts. -The valve driver needs 12-14volts. So in the end I'm looking for someone who can refine (fix) the current sketch I'm using, as well as assist in creating (modifying the current shield I created in Eagle) the proper circuit to power everything and read all the data.

Hello! I will make the pcb design as asked by you and make the necessary corrrections as needed. I had understod the features you mentioned like: -LCD Display (installed) and currently reads Gas Pressure in kPa and Total Gas %. -LCD Display a scale on bottom of screen that displays on a scale between 0-5 what the current gas setting is. -Potentiometer or Rotary Encoder for controlling gas pressure (Proportion valve with driver) -As for hardware, I have a small PCB that converts the 4-20mA signal from the gas gauge to higher voltage for Arduino to read - This needs 9volts. -The valve driver needs 12-14volts.

Hello, I can help you put your design on the right track. For your input 4 - 20mA we can make an other circuit that will output 5V max so the Arduino can read it. For the 14V output you can use a small relay or a transistor it depends if you want to here a click sound when the output is turned on. About me: I have 13 years experience in PCB design and worked on a lot a different projects from portable Heaters to complicate 1000 pin processors boards. Best Regards, Alex
