Hello everyone
I have
Mma7361 sensor. I am testing with a multimeter its stable but with arduino adc it giving wrong Datas.
When moving sensor with multimeter its true datas. But adc they are wrong. Giving a data and decreasing randomly. When no Move its still changing
Code?
Schematic?
And ... what does the sensor do?
...R
It is an accelerometer, 3 axis with analogue outputs.
If you are reading with a 10 bit ADC, then you will get a little noise on the line. That said it should be reasonably stable.

AWOL:
Code?

I tried arduino mega and arduino leonardo. I used example programme for adc.
/*
AnalogReadSerial
Reads an analog input on pin 0, prints the result to the serial monitor.
Attach the center pin of a potentiometer to pin A0, and the outside pins to +5V and ground.
This example code is in the public domain.

// the setup routine runs once when you press reset:
void setup() {
// initialize serial communication at 9600 bits per second:
Serial.begin(9600);
}
// the loop routine runs over and over again forever:
void loop() {
// read the input on analog pin 0:
int sensorValue = analogRead(A0);
// print out the value you read:
Serial.println(sensorValue);
delay(1); // delay in between reads for stability
}
Its basically 5v to 5v
gnd to gnd
x to analog 0
How long do you think delay(1) lasts for?
And what output are you getting?
