Every microbit has a 2.4 GHZ radio module bulit into the CPU.
Below is demo of what we are going to do in this short tutorial–send a number of radio waves from one microbit to the other:
Radio Group. Both microbits must be set to the same group number. I chose the number 5. Just make sure you set that first (on start).
Most common error is not setting the same radio group on both microbits.
If/else if / else with a variable
Create a variable and set it to a random number:

Some Examples of what people have done before:
Use onshape to generate a winter themed 3-d drawing. The more complex, the more points.
Ideas include : snowflake, snowman, Hanukkah candles, christmas tree with presents
Example of 5 out of 5 initial outline
Example of 3 out of 5
Some good actual examples of completed projects
That’s it, no extrudes or anything, just practice importing an image to onshape and tracing it.
Units : MM
Step 1) Inscribed Triangle . Dimensioned to 22. Centered at origin
Step 2) Make 1 vertex of triangle vertical with the origin. This will define the shape
Step 3) This is what your shape should now look like :
Step 4) Use the scissor tool to delete the top 3rd of the circle
Step 5) Connect the 2 points (make sure it’s defined)
Step 6) Perform 2 extrudes (25 and 35). :
Step 7) Fillet as shown:
Step 8) Add a shell:
Step 9) Final product:
Workspace Units: MM
Step 1) Create a new sketch on the front plan and create the following sketch. All share centered at the origin:
(Click image to enlarge)
Step 2) Extrude 1:
Step 3) If sketch 1 is hidden, make sure to show it
Step 4) Extrude 2:
Step 5)Fillet :
Step 6) Add a chamfer:
Result
Step 1) Create a 25, 30 , 40 and 42 MM circles all centered at the orig
Step 2) Add a single circle on the right that has a radius of 35.
Step 3) connect centers with construction line. Make sure that the blue lines are coincidental to the circles
tip: if you draw a line , you can use the ‘q’ button to change it to a construction line!
Step 4) Make the blue lines symmetric to the construction line and at a 9 degree angle
Step 5) The center of the circles should be dimensioned to 44:
Step 6) Each part of the circle on the left should be an extrude. The outermost starts at 10MM, then 15MM, 20, 25 MM:
Step 7) Connect the two end circles with a 2 MM extrude. The right side is 25 MM:
Step 8)create the variable as shown below:
Step 9) Add a fillet to all the circles edges. Set its amount to the variable len as shown. This video shows you how to use a variable and then change the variable:
