+Use pins P0, P1 and P2 to change the display by creating a circuit with your body.
+
+## Step 1
+
+Use [on pin pressed](/reference/input/on-pin-pressed) to show a random number
+when pin P0 is pressed (hold the GND pin with other hand):
+
+```blocks
+input.onPinPressed(TouchPin.P0, () => {
+    basic.showNumber(Math.random(11));
+});
+```
+## Step 2
+
+Show a string when pin P1 is pressed:
+
+```blocks
+input.onPinPressed(TouchPin.P0, () => {
+    basic.showNumber(Math.random(11));
+});
+input.onPinPressed(TouchPin.P1, () => {
+    basic.showString("LOVE?");
+});
+```
+
+## Step 3
+
+Show a heart when pin P2 is pressed:
+
+```blocks
+input.onPinPressed(TouchPin.P0, () => {
+    basic.showNumber(Math.random(11));
+});
+input.onPinPressed(TouchPin.P1, () => {
+    basic.showString("LOVE?");
+});
+input.onPinPressed(TouchPin.P2, () => {
+    basic.showLeds(`
+        . # # # .
+        # # # # #
+        # # # # #
+        . # # # .
+        . . # . .
+        `);
+});
+```
