Current sensor (ACS712) with arduino

[johnerrington]

As @Idahowalker has said we need a chematic - even if its something as simple as a pencil sketch.

How to make a schematic you can post.

When you submit a question on the forum you will usually need to add a schematic (circuit diagram). The tutorial that follows will explain some ways to create a useful image; however lets start by explaining how to add the image to your post. Its easy. Having created the image all you need to do is : Save the image somewhere convenient - maybe your desktop Start your post, and place the cursor (insertion point) where you want the image to be shown; [upload image to forum] 3: click th…

we also need to know EXACTLY what hardware you are using - with a link to a data sheet or suppliers documentation.

Including - particularly - the "arduino"

In your code you are averaging 10,000 values; really its better to use a power of 2 for your "Count" - and 64 is plenty

double Vout = 0;
double Current = 0;
int Count = 64;
long Vsum; //aggregated values read from adc

and 
void loop() {
Vsum=0;
for(int i=0; i<Count; i++){
Vsum += analogRead(A0); // add em up as integers
delay(27); //chosen to avoid mains frequency readings; or eg 7 or 13
}
Vsum = Vsum / Count;  //dividing average for getting averaged voltage reading value
Vout = Vsum *5.0 /1024; 

//print the reading.
