Re: Can the sensors be connected to a third-party board?

adjusted the code, as the LED was not getting goo dnumbers, however: fadeValue = (int)(0.255 * val); analogWrite(9, fadeValue); Didn't change anything of the fact that readings dont seem to come in right. Do I always have to connect the contact ends into the double-cable sockets or is it enough for ...

Re: Can the sensors be connected to a third-party board?

Okay I am using 100KOhm and the below script : int analogPin = 1; // potentiometer wiper (middle terminal) connected to analog pin 3 // outside leads to ground and +5V int val = 0; int ledPin = 9; // LED connected to digital pin 9 int fadeValue = 9; // LED connected to digital pin 9 void setup() { /...

Re: Can the sensors be connected to a third-party board?

I found this: http://www.raltron.com/cust/tools/voltage_divider.as

but it tells me to get different resistors e.g. R1 = 4.7kOhm ; R2 = 2.2kOhm(approx)

Re: Can the sensors be connected to a third-party board?

I thought as much.

How do I wire this:
To get the VSS = VCC/2 voltage, you can either use a resistive voltage divider (with R1=R2) or a voltage regulator.

I have various resistors. Is that what i would need?

Arduino Nano and ECG

So I hooked up the ECG to an Arduino Nano. GND & VCC (on3.3V) A4 of the sensor is connected to the Arduino's A1 analog input pin. I connected the dual sherlock contacts. for visual check I added an LED to transform the 0-1000 from the sensor(right?) to be turned into a 0-255 brightness LED flick...

Re: Can the sensors be connected to a third-party board?

How would I connect the ECG's A4, VSS and GND,VCC to an arduino (nano)

I assume the GND VCC are obvious on 3,3V, but what about the two others?

Raspberry PI

More mobile than using this on a PC, why not have a Python version that runs on a PI?

Re: Where are the Java, Android OS, and remaining APIs?

If you have an Android version, could you put a sample app on the marketplace/google play?

Step by Step Manual

Hello Bitalinos, nice site, like the look, but I am having a hard time finding my way around the setup. The Software and Hardware manual are a bit spec only. What I really didn't find is the download link for the SignalBit software. There is generally very little info on if this is a PC or OSX app o...
