Need some help getting started

[Lucas Cronin]

Hello, I am new to Arduino so I could use some help.



I see there is a parts list here: viewtopic.php?f=24&t=39

Are there any other parts I will need? (I don't have scrap parts around since I have never done this before)



Are these the only circuits I need to know, or are there more?

viewtopic.php?f=24&t=40

viewtopic.php?f=24&t=41

viewtopic.php?f=24&t=36



How do I get it to work with LDD drivers and controllable fans?


Besides those links is there any more information I should know?

[Lucas Cronin]

How do these parts look?

SainSmart Mega2560 + 3.2" TFT LCD Shield + Touch Screen SD Reader for Arduino 2560 Kit

SainSmart I2C RTC DS1307 AT24C32 Real Time Clock (Will this RTC work with the kit above?)

Mini ENC28J60 Ethernet LAN / Network Module

DS18B20 Temperature Temp Sensor

PCF8575 I2C I/O Extension Shield Module

16 Channel 5V Relay Module Board

Ezo pH Stamp

Single Circuit Carrier Board (I only want to measure pH)

Prototype Shield DIY KIT

Jumper Cables

Do I need any jacks, connectors, and boards to attach them too? (I see RedTop here has some float switches on 3.5mm jacks attached to a small board)

Hi!!

I'm not an expert and I am also as you starting with Arduino but will try to help you with something

The libraries used by Ferduino have some conflict with that rtc
The thernet ENC28J60 does not already support you need to find Ethernet W5100
LCD'm not sure if it worked, I think you would have to change code
And if that relays board is low level active, you will need two ULN2803

Best regards and forgive my poor English

Hello, thank you for the help!

I will swich to the TFT + RTC and the LCD that Fernando recommends in the parts list:

TFT shield with RTC

TFT LCD Screen

I will also use the W5100 instead of the Ethernet module.

What is "low level active"? Would these be better relays?

Hi!

Welcome Lucas!

How do I get it to work with LDD drivers and controllable fans?

Here you cand find projects to LDD board.

16 Channel 5V Relay Module Board

This relay board should be active low, use a circuit like this:

http://www.ferduino.com/forum/gallery/i ... age_id=119

The 0 volt goes to relay board INPUT (1 - 16).

Prototype Shield DIY KIT

This item is incompatible.

Do I need any jacks, connectors, and boards to attach them too? (I see RedTop here has some float switches on 3.5mm jacks attached to a small board)

For this type of item you need find the best option for your project.

Best regards.

Is the PCF8575 that is on the parts list intended to be used with the relay board, or will I need an extra?

How about this one?

Since I am new to Arduino and electronics I do not know what to look for. Can you recommend what you would use?

Thank you for the help.

[Fernando Garcia]

This module is ok.

http://www.ebay.com/itm/New-PCF8575-I2C ... 2599fcdc95

Add for your list 2 ULN2803 only.

For prototype shield, please look to images available on topic about pat list.

1. A bit confused, do I need x1 or x2 PCF8575?


2. These are the closest things I can find to the relay board on the part list, but they have a reset button on them. Will any of these work?:

3. What MOSFET do I use with 700mA and 1000mA LDD drivers on this power supply?

[Fernando Garcia]

Hi!

1 - Only one PCF8575.

2 - This models are too much different!

3 - The MOSFET isn't needed if you will use the LDD. Moreover the model is very clear on schematic (IRLZ44N).

Check it: viewtopic.php?f=25&t=218

Best regards.

[Lucas Cronin]

Very helpful Fernando!

I think I found the protoshield finally. http://www.ebay.com/itm/181151830516?_mwbanner=1

A few more questions if that is OK:

1. Do I need a driver or MOSFET to use fans on PWM?

2. What power supply do I use with Ferduino?

3. What gauge wire do I use with the Ferduino?

4. Do you know the name of the plug used on RedTop's Ferduino? EDIT: I found it's DE-9 connector

5. Do I need any of these parts:

Ferduino Description wrote:

9 Jack phone 3.5 mm (6 are connected in analog pins and has pull up resistor of 10K and LEDs in parallel to be used with float switches, 3 are connected to a digital pin and has a resistor pull up of 4.7K Ohm to be used with temperature sensors in parasite mode);
2 Jack RJ45 (1 connected in an ULN2003 that’s controlled by analog pins, this circuit allow control devices untill 50V / 500mA, 1 connected to 3 analog pins and 4 digital pins);
1 Header 2 x 20 connected to hex buffers that allow connect TFT’s of 3.3V directly;
1 Connector DB37 in parallel with the header 2 x 20 that allow connect TFT’s of 3.3V using a serial cable;
2 Jack RJ11 (1 connected to digital pins, GND and 5V);
1 LAN;
1 Connector DB25 (connected to 2 ULN2803 controlled by an expander I2C)
4 Connector BNC (connected to 4 sockets to be used with circuits from Atlas Scientific).

[Fernando Garcia]

Hi!

1 - You need look the circuits here: viewtopic.php?f=24&t=40

2 - Any voltage between 7 and 12 V.

3 - For control a cat5 is enough.

4 - The connector is DB9.

Best regards.

[Lucas Cronin]

1. Instead of using a DB9 connector, is it OK to use Cat5 cords joined via coupler?

(Arduino PWM --> Cat5 cord --> coupler --> Cat5 cord --> LED, fan, etc.)


2. Is this the right ULN2803?


3. Do I need this:

4. Is this Mega OK?

[Fernando Garcia]

Hi!

1 - As I told before use the best system for you;

2 - Yes;

3 - Vide 1;

4 - Yes.

Look to examples available on this forum: http://www.ferduino.com/forum/viewforum.php?f=18

Best regards.

Many thanks Fernando. I will start a "Show your controller" thread when my parts arrive.
