Sparki’s new eyes

Hi guys

So today I got my new ultrasonic range finder for Sparki-one with 3 pins instead of 4.

My poor soldering skills had meant that although I had fixed Sparki (here) he soon broke again.

The 4 pin ultrasonic range finder did not connect to the expansion port as there was not enough ports for one of the pins, so I opted for a 3 pin replacement to connect to the expansion port, instead of the board itself which is how Sparki was originally set up.

So he’s now set up and all ready to go!

Although I now have to re-code everything I have ever worked on…

So I began, but now I’m awfully stuck.

Using the digital pin 1 (TX) does not seem to make a change to the reading given on the screen , it simply remains at 1….although this is the code I ahve found for a 3 pin sensor online…

so I hooked it up to the Analogue pin 8 instead (and moved the touch sensor that was there to the digital pin RX which works great) but on there it flickers between 383/384/385 and 0. To test it I edited a previous code:

#include <Sparki.h>

void setup()
{
}
void loop()
{
	
		sparki.servo(0);
                float distance=analogRead(8);
                sparki.clearLCD();
      sparki.print(distance);
      sparki.updateLCD();
      delay(2000);
		if((distance<380))
		{
			delay(1000);
			sparki.RGB(0,255,0);
			sparki.moveForward(10);
			sparki.beep(540, 1000);
		}
		sparki.servo(0);
		if((distance>0))
		{
			delay(1000);
			sparki.moveRight(10);
		}
	}

But it appears that the 0 is random, and not connected to the distance measured at all….

So now I’m feeling frustrated 😦 😦

any help???
