 # Reset
 
-Reset the BBC micro:bit (as if you pushed the reset button on the back of the device), which causes the program to start again.
+Reset the BBC micro:bit and start the program again.
+
+This function is like pressing the reset button on the back of the micro:bit.
 
 ```sig
 control.reset()
 ```
 
+### Example
+
+This program will count as high as you like when you press button `A`.
+When you get tired of counting, press button `B` to reset the
+micro:bit and start the program over.
+
+```blocks
+let item = 0;
+basic.showNumber(item);
+input.onButtonPressed(Button.A, () => {
+    item = item + 1;
+    basic.showNumber(item);
+});
+input.onButtonPressed(Button.B, () => {
+    control.reset();
+});
+```
+
+#### ~hint
+
+This program works better on a real micro:bit than in the simulator.
