Current Calculator Example Script
Here is a micro:bit current calculator that you can run to check the current a resistor conducts based on its resistance value and the voltage measured at its leads.
- Enter the calculate_i_from_v_and_r script into the python.microbit.org editor.
- Update the Script Name field and then click Load/Save → Download Project Hex.
- Click Connect and select the micro:bit and connect if a popup appears.
- Click Flash to load the script into the micro:bit.
# calculate_i_from_v_and_r
from microbit import *
while True:
text = input("Enter volts: ")
V = float(text)
text = input("Enter ohms: ")
R = float(text)
I = V / R
print("I = ", I, "A")
print()
Test the Calculator
