Touch Control ?
« on: Nov 28 2014 08:53 »
Have just seen this being promoted in an email received from
Doesn't give much info (no tech PDF download offered) but it seems to suggest that the 12 inputs can be triggered by "touch" if connected to a printed (in conductive paint) diagram.
So, would it be of use on a control panel .... I am thinking signal and point set routes by "touch" rather than switches?
Anyone know what the output capabilities of this might be....presumably only enough power to trigger a miniature 5V relay?

My fellow Members, ask not what your Society can do for you, ask what you can do for your Society.

I wrote to these guys this morning regarding your application.

This was the response -

"Thanks for your question. We have had the following feedback from Bare Conductive regarding your enquiry:

PWM pins are digital pins which can be configured as outputs with a variable voltage.

The Touch Board has the same number of digital outputs as a standard Arduino Leonardo, plus the sound functionality.

This link contains the pin map which should answer all pin related questions:

To achieve what you want Bare Conductive suggest that you would need to write your own code or modify their code found on or

We hope this helps and we will be adding more resources to the product page shortly.


Pulling the web pages for the Leonardo

The hardware page states that each of the 20 digital i/o pins on the Leonardo can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. They operate at 5 volts. Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor (disconnected by default) of 20-50 kOhms.

In addition, some pins have specialized functions: see this link on

Typical engineers website, hard to follow and find the information you want as the various graphics formats confuses easily - either that or I am getting too old for this stuff.

Good luck.

Thank you very much for getting that info for me....Rapidonline certainly live up to their name when it comes to dealing with requests!

I will look at the links later today (am working on my G32 scale Ruston Proctor ZLH at moment) and see what I can make of it all.

Evaluate first John, this is a warning to touch control as there are devices which only respond to skin ( i.e. uncovered fingers ). If using a gloved hand may not work. If your hands are filthy like oily, greasy or muddy after servicing trains or doing gardening then a build up of detritus on controls will give false indications. My first thoughts are indoors only rather than all weather application unless the kit is "industrialised".

Last thing you want are points re-setting due to false triggers.

Pessimism? Yes, but have had experiences of things that cannot be explained otherwise, with various types of user interfaces.

Flicking switches or pulling levers to me is a bit "old Tech" but railway like & understandable & safe.

Looks interesting though & if you want something innovative, modern, high-Tech then this could be the way to go once the evaluation & acceptance trials are to your satisfaction. Good luck with it.
