HANDS-ON PROJECT


                  PROJECT NAME: Step Counter Gadget with Micro:Bit

                  Objective:

                     Design and build a step counter using Microsoft MakeCode for Micro:bit.

                     Program the Micro:bit  to  detect  motion,  count  steps,  and show the total  on its  LED
                    screen.

                     Learn how to use sensors, variables, and loops through hands-on coding.
                  Step-by-Step Instructions

                  Step 1: Setting Up the Micro:bit Program


                  Open MakeCode Editor:

                     Go to MakeCode for Micro:bit.

                     Start a new project and name it “Step Counter.”

                  Design the Code:


                     Use blocks to:
                    o  Detect motion using the Micro:bit’s built-in accelerometer.

                    o  Count steps using a variable.

                    o  Display the step count on the LED screen.


                  Basic Blocks to Include:

                     On Start Block: Initializes the step count to zero.

                     On Shake Block: Increases the step count when the Micro:bit is shaken.
                     Forever Block: Continuously displays the step count.


                  Example Code:

                  On Start:

                     Create a variable stepCount and set it to 0.

                     Drag the on start block and attach the set stepCount to 0 block.
                  On Shake:

                     Drag the on shake block from the input category.

                     Attach the change stepCount by 1 block to increment the counter.
