Analog input

weird analog values

hi ... euh i have a problem while i read analog inputs the micro controler ( arduino pro mini)

 

.... when i tried to read the analog input with a maxsonar (even tried with a simple resistor) when i use the serial monitor

I get data that resembles more drawing  than digits

 

....anybody heard of something like that

 

thanks

Analog input - Not getting good readings

I am using a Sharp IR Analog Sensor (2 different ones, in fact) and the readings I'm getting on both are not 'correct'.  I'm using a PICAXE 28 & a Sharp GP2D120XJ00F or GP2Y0A21YK.
