+# Getting started
+
+Are you ready to build cool BBC micro:bit programs? For each challenge, reorder the blocks to recreate the program.
+
+* If you haven't done so, open [https://m.pxt.io](/) and create a new **Blocks Editor** project
+
+## Basic
+
+### Show leds
+
+Use the blocks below to draw a figure on the screen. You can redo the smiley face or try something else!
+
+```shuffle
+basic.showLeds(`
+    . . . . .
+    . # . # .
+    . . . . .
+    # . . . #
+    . # # # .
+    `)
+```
+
+To transfer your code to the BBC micro:bit, 
+* connect your micro:bit to the computer using the USB cable
+* click on **Download**
+* drag&drop the **.hex** file into the **MICROBIT** drive
+* wait till the yellow light is done blinking!
+
+### Show animation Forever
+
+Show one image after the other to create an animation.,
+
+Reorder the blocks to make the micro:bit show a happy, then unhappy face.
+```shuffle
+    basic.showLeds(`
+        . . . . .
+        . # . # .
+        . . . . .
+        # . . . #
+        . # # # .
+        `)
+    basic.showLeds(`
+        . . . . .
+        . # . # .
+        . . . . .
+        . # # # .
+        # . . . #
+        `)
+```
+
+### Repeat forever
+
+Use the ``forever`` block to repeat your code and have a continuous animation.
+
+Unsuffle the blocks to create a happy, unhappy animation.... or changes the image to make it your own!
+```shuffle
+basic.forever(() => {
+    basic.showLeds(`
+        . . . . .
+        . # . # .
+        . . . . .
+        # . . . #
+        . # # # .
+        `)
+    basic.showLeds(`
+        . . . . .
+        . # . # .
+        . . . . .
+        . # # # .
+        # . . . #
+        `)
+});
+```
+
+### Your turn now!
+
+Use the blocks ``show leds`` and ``forever``
+to create your own custom awesome animation!
+
+## Inputs
+
+### Button A and B
+
+Unshuffle the blocks so that the micro:bit shows "YES" when button A is pressed, and "NO" when B is pressed. 
+The key idea is that all the blocks nested under `on button ... pressed` will run when that button is pressed.
+
+```blocks
+input.onButtonPressed(Button.A, () => {
+    basic.showString("AAAAA");
+});
+```
+
+Try to unshuffle those blocks:
+```shuffle
+input.onButtonPressed(Button.A, () => {
+    basic.showString("YES");
+});
+input.onButtonPressed(Button.B, () => {
+    basic.showString("NO");
+});
+```
+
+### Shake
+
+Using the data from the **accelerometer**, it is possible to detect that the BBC micro:bit is being shaken.
+
+Unshuffle the code to display a frownie when shaken.
+```shuffle
+input.onGesture(Gesture.Shake, () => {
+    basic.showLeds(`
+. . . . .
+. # . # .
+. . . . .
+. # # # .
+# . . . #`);
+});
+```
+
+### Tilting
+
+Aside from shake, it is also possible to detect tilt left and right, logo up and down or face up and down.
+Let's build a rock paper scissors game where you turn the micro:bit left to display paper, right to display scissors and down to display rock.
+
+Unshuffle and try this code on the micro:bit itself!
+```shuffle
+input.onGesture(Gesture.TiltLeft, () => {
+    basic.showLeds(`
+# # # # #
+# . . . #
+# . . . #
+# . . . #
+# # # # #`);
+});
+input.onGesture(Gesture.LogoDown, () => {
+    basic.showLeds(`
+. . . . .
+. # # # .
+. # # # .
+. # # # .
+. . . . .`);
+});
+input.onGesture(Gesture.TiltRight, () => {
+    basic.showLeds(`
+# # . . #
+# # . # .
+. . # . .
+# # . # .
+# # . . #`);
+});
+```
+
+### Pins
+
+It is possible to use the pins (big metal bar at the bottom of the board) as button. Hold the ``GND`` button with one hand and press the ``0`` pin 
+(called ``P0``) with the other hand to trigger a pin pressed.
+
+Unshuffle the blocks to display a smiley when pin ``P0`` is pressed.
+```shuffle
+input.onPinPressed(TouchPin.P0, () => {
+    basic.showLeds(`
+. . . . .
+. # . # .
+. . . . .
+# . . . #
+. # # # .`);
+});
+```
+
+### Your turn now!
+
+Use the scree, buttons, gestures, pins to create a fun game using the micro:bit.

+# Seismograph Activity 
+
+### ~avatar avatar
+
+In this project, you will build your own seismograph. 
+
+## What you'll need: 
+
+* micro:bit 
+* USB cable
+* Scissors
+* Glue gun
+* String
+* Cup (Plastic or Paper)
+* Magnet
+
+Welcome! This activity will teach how to use the micro:bit to chart the strength of the acceleration. Let's get started!
+
+1. Setup Cup: Use scissors to cut a usable window on the cup, which will be a square sized hole at the lid side of the cup. Use scissors to create a small hole in the center of the base of the cup. 
+
+2. Fasten Magnet: Fasten end of the string to the magnet with glue
+
+3. Secure String: Fasten string to base of the cup and hang the remaining string outside the base of the cup. 
+

+
+We will measure `acceleration (mg)` in terms of strength. Get the acceleration value (milli g-force), as measured in strength.
+
+```blocks
+input.acceleration(Dimension.Strength);
+```
+
+### ~
+
+6. 
+
+Use the plot bar chart to visualize the acceleration on the LED screen of the micro:bit in the specified range. You implement plot Bar Graph to display a vertical bar graph based on the "value" and "high" value. Then you must insert acceleration in based on strength. 
+
+```blocks
+basic.forever(() => {
+    led.plotBarGraph(input.acceleration(Dimension.Strength), 0);
+});
+
+```
+
+### ~
+
+7. 
+
+Finally, we subtract the gravity from acceleration strength. 
+
+```blocks
+basic.forever(() => {
+    led.plotBarGraph(input.acceleration(Dimension.Strength) - 1023, 0);
+});
+
+```
+
+### ~
+
+8. 
+
+Notice that making vibrating the object below the micro:bit changes the values and the line appears as a wave to display the value of the strength as measured in milli-gravities. By making the object below the micro:bit vibrate, you will observe changing values of the micro:bit. Also, the LEDs shown on the Bar Graph fluctates based on the movement of the micro:bit strength.

+# Extensions
+
+You can publish libraries (also known as packages or extensions)
+that users can then add to their scripts. These typically
+provide a driver for a particular hardware device you can connect
+to a microbit.
