+# Send Number
+
+Broadcast a (name,number) pair to other micro:bits connected via ``radio``.
+
+### Parameters
+
+* name - a string to send
+* num - a number to send.
+
+### Simulator
+
+This function only works on the micro:bit, not in browsers.
+
+### Example: Broadcasting acceleration
+
+This example broadcasts the value of your micro:bit's ``acceleration`` in the `x` direction 
+(left and right) to other micro:bits.
+This kind of program might be useful in a model car or model rocket.
+
+```blocks
+input.onButtonPressed(Button.A, () => {
+    radio.sendValue("acc",input.acceleration(Dimension.X))
+})
+```
