+# blink blocks activity
+
+Turn an LED on and off with forever 
+
+### ~avatar avatar
+
+```sim
+basic.forever(() => {
+    led.plot(2, 2)
+    basic.pause(500)
+    led.unplot(2, 2)
+    basic.pause(500)
+})
+```
+Let's build a blinking light!
+
+### ~
+
+Have you ever tried to blink a flashlight at night? The concept is fairly simply: turn on the light, wait for a little, turn off the light, wait again, and repeat. That's exactly what we need to code to get a blinking LED.
+
+Let's start by adding a line of code that turns on the LED at position 2, 2.
+
+```blocks
+led.plot(2, 2)
+```
+
+Run your script to make sure it's correct. Then, let's add code to `pause` 500 milliseconds and turn off the LED.
+
+```blocks
+led.plot(2, 2)
+basic.pause(500)
+led.unplot(2,2)
+```
+
+We've got the LED blinking once. Let's add another pause and turn on the LED again.
+
+```blocks
+led.plot(2, 2)
+basic.pause(500)
+led.unplot(2, 2)
+basic.pause(500)
+led.plot(2, 2)
+```
+
+The current code works but it only blinks once! We are going to use a `forever` loop and move the code inside it to repeat it forever. We've dropped the second `plot` line since we don't need it in the loop.
+
+```blocks
+basic.forever(() => {
+    led.plot(2, 2)
+    basic.pause(500)
+    led.unplot(2, 2)
+    basic.pause(500)
+})
+```

+# blink blocks challenges
+
+Coding challenges for the blink tutorial 
+
+## Before we get started
+
+Complete the [blink](/lessons/blink/activity) activity and your code will look like this:
+
+```blocks
+basic.forever(() => {
+    led.plot(2, 2)
+    basic.pause(500)
+    led.unplot(2, 2)
+    basic.pause(500)
+})
+```
+
+### Challenge 1
+
+Let's display a "smiley face" on the screen! We'll start by plotting the eyes.
+
+Add `plot(1,1)` and `plot(3,1)` under `plot(2,2)` ; then add `unplot(1,1)`, `unplot(3,1)` and `unplot(2,2)` after `pause`. When you're ready, don't forget to run your code to try it out!
+
+```blocks
+basic.forever(() => {
+    led.plot(2, 2)
+    led.plot(1, 1)
+    led.plot(3, 1)
+    basic.pause(500)
+    led.unplot(2, 2)
+    led.unplot(1, 1)
+    led.unplot(3, 1)
+    basic.pause(500)
+})
+```
+
+### Challenge 2
+
+Let's add the code to plot the mouth by using `plot` and `unplot` to the following coordinates: (1,4), (2,4) and (3,4). When you're ready, don't forget to run your code to try it out!
+
+```blocks
+basic.forever(() => {
+    led.plot(2, 2)
+    led.plot(1, 1)
+    led.plot(3, 1)
+    led.plot(1, 4)
+    led.plot(2, 4)
+    led.plot(3, 4)
+    basic.pause(500)
+    led.unplot(2, 2)
+    led.unplot(1, 1)
+    led.unplot(3, 1)
+    led.unplot(1, 4)
+    led.unplot(2, 4)
+    led.unplot(3, 4)
+    basic.pause(500)
+})
+```
+
+### Challenge 3
+
+Let's keep using `plot` to convert the mouth into a smiley face.
+
+```` bitmatrix
+0 0 0 0 0
+0 1 0 1 0
+0 0 1 0 0
+1 0 0 0 1
+0 1 1 1 0
+````
+
+### Challenge 4
+
+Let's make it blink a bit faster. To do so, we need to reduce the amount of time used in ``pause`` to 100 milliseconds.
+
+### Challenge 5
+
+Create your own image by changing the coordinates in `plot` and `unplot`!

+# blink blocks quiz answers
+
+Learn how to create a blinking LED script.
+
+This is the answer key for the [blink quiz](/lessons/blink/quiz).
+
+## 1. Describe what `plot` does?
+
+Answers will vary. In general, plot refers to the code that turns on a specific LED. We specify the LED using x, y coordinates.
+
+## 2. Draw which LED is ON after running this code
+
+```blocks
+led.plot(2, 2)
+
+```
+
+![](/static/mb/lessons/blink-0.png)
+
+By default, the position of an LED on *Blink Tutorial* is set to the centre of the screen. This code turns on the centre LED
+
+## 3. Draw which LED is ON after running this code
+
+```blocks
+led.plot(0, 0)
+
+```
+
+![](/static/mb/lessons/blink-1.png)
+
+This code turns on specific LED. Plot turns on the specified LED on the LED screen. We specify the LED using x, y coordinates.
+
+* ``x`` - the x coordinate or horizontal position (0)
+* ``y`` - the y coordinate or vertical position (0)
+
+## 4. Draw which LED is ON after running this code
+
+```blocks
+led.plot(4, 4)
+
+```
+
+![](/static/mb/lessons/blink-2.png)
+
+This code turns on specific LED. Plot turns on the specified LED on the LED screen. We specify the LED using ``x``, ``y`` coordinates.
+
+* ``x`` - the x coordinate or horizontal position (4)
+* ``y`` - the y coordinate or vertical position (4)
