I need to finish electronic scheme and preparation for PCB, so I can build board. I would like to put Atmega 328 with arduino preloaded on PCB. I have 4 temperature sensors (DS18B20), one matrix keyboard and 4 relay control and one LCD display 20x4. Input power supply is 24 volt
It has to be done like this:
Atmega 328 - all around (crystal, capacitors, reset button), power controler (24 to 5 V), connector on RX and TX so I can program it over USB to serial (D0 and D1 on Atmega 328, gnd and +5V).
7 pin connector for matrix keypad - (on pins D2-D8)
4 pin connector for LCD 20x4 screen (they are conected to A4, A5, GND and 5 V) A4 and A5 are SCL and SDA
3 - DS18B20 temperature sensors have to be connected over some kind of connector (RJ 9 or RJ 11). they have to be connected to A1, A2 and A3 (4,7 kohm resistor has t0 be between +5 and data pin) - female RJ9 or RJ11 should be on the board .
1 - DS18B20 temperature sensor has to be directly on board to get around temperature and it is connected to A0 pin.
Pin D9, D10, D11 and D12 should control 4 relay. Relays connected on PIN D9 and D10 control two FANs on 12 Volts (so it is important to build 24 to 12 V circuit)
Relays connected on PIN D11 and D12 control two heaters on 24 Volts
Relays need to have connectors so heaters and fans can be connected (screw connector terminal block)
Hello.
Greetings of Peace.
I have great experience in developing custom electronics systems. I have developed an automation for a solar thermal power plant and have created many other industrial solutions. I have been mostly working with Arduino only and hold a good knowledge of it. I have also won World Arduino UNO WiFI Contest. Will design all sch, layout, gerber data in Eagle files only.
I assure you the best quality work.
Thus, I can give you a one-stop solution for prototyping, PCB design, assembly, and manufacture. I would like to have the opportunity to work with you and would love to discuss your requirements in detail.
Let's get in touch and get it done.
Please have a look at my portfolio for my detail work.

Hello, how are you? I hope you have a bright day/evening from your side. I have read the details provided, but please contact me so that we can discuss more on the project. I believe I have the required skills in this case. I will work on your requirements personally since I do not outsource to third parties, this guarantees you high-quality work that is delivered on time. You can also request for revisions till you’re fully satisfied with the work. I believe research is a passion and not a money making business where people will deliver low-quality work just to get paid. Try my services, and you will never regret. Waiting for your kind response
Hello. I work with Atmega 328 a lot (very popular chip supported Arduino IDE) and all your other components. I even coudnt count how much PCBs with this chip I ve designed.
I am ready to make board design for you right now.
Regars, Bogdan.
I have experience in 3 programs and for 7 years. Check my portfolio, Facebook page and website www.upperbandtech.com. I can easily do the connections and optimize for the current and size. I will set the width and the components' placement for the max. efficiency and compactness and min. cross-talking.
I use eagle on couple of my projects in university. I can make it work.
