+# Digital Read Pin
+
+The digital read pin function. #digitalreadpin #docs
+
+Digitally read the specified [pin](/microbit/device/pins) (``P0``, ``P1``, ``P2``, ...) as digital. **Some pins are also used by the display, read the [pin documentation ](/microbit/device/pins) carefully.**
+
+```sig
+pins.digitalReadPin(DigitalPin.P3)
+```
+
+### Parameters
+
+* name - the pin name ``P0``, ``P1``, ``P2``, ...
+
+### Returns
+
+* [Number](/microbit/reference/types/number) - 0 or 1
+
+### Example: football score keeper
+
+The following example reads `P0` to determine when a goal is scored. When `P0 = 1`, the code uses `digital write pin` to play a buzzer sound:
+
+```blocks
+let score = 0
+basic.showNumber(score)
+basic.forever(() => {
+    if (pins.digitalReadPin(DigitalPin.P0) == 1) {
+        score++;
+        pins.digitalWritePin(DigitalPin.P2, 1)
+        basic.showNumber(score)
+        basic.pause(1000)
+        pins.digitalWritePin(DigitalPin.P2, 0)
+    }
+})
+```
