[Swlug] An interesting time with an accelerometer

[Rhys Sage]

I'm working with an accelerometer with the Pi Pico. I'm getting output from it but I'm not really sure whether the output is correct. The code came from Github and likely does not have a problem. I'm a bit perplexed by the output. It does not seem to me to be normal output - what do you think? Is there a problem with the accelerometer? It's the same one from the video I made the other day.

Place breadboard on one end then hit enter

The code came from here: https://microcontrollerslab.com/mpu6050-raspberry-pi-pico-micropython-tutorial/#MicroPython_MPU6050_Getting_Accelerometer_Gyroscope_and_Temperature_values

The only change I made was to the output display and this is the code...

from imu import MPU6050
from time import sleep
from machine import Pin, I2C




def Printout():
    ax=round(imu.accel.x,2)
    ay=round(imu.accel.y,2)
    az=round(imu.accel.z,2)
    gx=round(imu.gyro.x,3)
    gy=round(imu.gyro.y,3)
    gz=round(imu.gyro.z,3)
    tem=round(imu.temperature,2)
    print("ax",ax,"\t","ay",ay,"\t","az",az,"\t","gx",gx,"\t","gy",gy,"\t","gz",gz,"\t","Temperature",tem,"        ",end="\r")
    sleep(0.2)
    


i2c = I2C(0, sda=Pin(0), scl=Pin(1), freq=400000)
imu = MPU6050(i2c)


input('Place breadboard flat then hit enter')
Printout()
print("\n")


input('Place breadboard on one side then hit enter')
Printout()
print("\n")


input('Place breadboard on the other side then hit enter')
Printout()
print("\n")


input('Place breadboard upside down then hit enter')
Printout()
print("\n")


input('Place breadboard on one end then hit enter')
Printout()
print("\n")


input('Place breadboard on the other end then hit enter')
Printout()
print("\n")


while True:
   Printout()
