Basics

Make sure you have installed the necessary driver for your computer:

To control a magnetic stirrer with the ika package, you need to identify the comport the device is when connected to your computer.

Example usage

Magnetic stirrer

import time
from ika.magnetic_stirrer import MagneticStirrer

port = 'COM5'
plate = MagneticStirrer(device_port=port)
plate.start_stirring()
plate.set_target_temperature(100)
time.sleep(10)
plate.set_target_temperature(200)
plate.stop_stirring()

plate.set_target_temperature(20)
plate.start_heating()
plate.set_target_temperature(19)
time.sleep(5)
plate.stop_heating()
