Re: How all works

Hi!

To invert the logic change:

bool MeanWell = true;


To:

bool MeanWell = false;


To limit the voltage in 3.3 and 1.8 V use a voltage divider with resistors.

Best regards.

Re: Touchscreen Problem ILI9481  [SOLVED]

Hi!

As I told this TFT is not in my part list and is not compatible with my code. There's no support for this hardware here.

Also you can buy a TFT 5" or 7" with resolution 800 x 480 and controller SSD1963 but you should edit the code by yourself.

Best regards.

Re: How all works

Hi!

I don't know the driver used in your LED light fixture so I can't tell you how to make the wiring.

The multiplexer for I2C BUS is not needed.

Please give enough information if do you want some help here.

Best regards.

Re: How all works

Hi!

Please be more specific. Your question is very generic.

Here you see the pin signed to each function.

Re: Module operation of Relays-2 and PCF8575

Hi!

The circuit seems ok to me.

When the PCF signal is HIGH what's the voltage in P0?

Re: Vortech MP10 Controller  [SOLVED]

Hi!

I don't know any way to hack a MP10.

Adding a RF module to your MP10 you can hack it as did Reef angel.

Then you can use this library to add functions to Ferduino code.

Re: Dosing Pump control Relays problem

Hi!

What's the reason to use a relay board for dosing pumps if an ULN2803 is more cheap and very small? Moreover the wiring is very simple.

Please show me the model of your relay board and pictures of your wiring.

Best regards.

Re: Stamps interference  [SOLVED]

Hi!

You can buy this isolator or I can sell this PCB for you.

The bare PCB is about $30 USD and components are 50$.

You will be responsible to buy components and assembly the board.

Best regards.

Re: Dosing And Wavemaker Pause for a while

Hi! Friend, I have explained it for you here . Every 5 - 6 seconds Arduino is checking others functions. Regarding dosage, the way to make it very accurated is using delay and during this time Arduino won't make anything else. You can try using millis but the code can hang in some part and a big amo...

Re: More Original LED Lights  [SOLVED]

Hi! Welcome Gordon! Firstly Ferduino haven't enough PWM pins for this application. You should add a module PCA9685 (16 channels) to expand the pins. There's something about it on forum. You should look for this pieces of code to see which variables you should add to expand LED channels. https://gith...
