+## Prior learning/place of lesson in scheme of work
+
+Learn how to **set brightness** of an image `set brightness` to set the brightness of the LED screen. We will be learning how to set the brightness of the LED screen using LED show LEDs, on button pressed and set brightness.

+* **show LEDs** : [read more...](/microbit/reference/basic/show-leds)
+* **on button pressed** : [read more...](/microbit/reference/input/on-button-pressed)
+
+## Objectives
+
+* learn how to set the brightness of the LED screen
+* learn how to run code when an input button is pressed
+* learn how to turn on all LEDs

+## Progression Pathways / Computational Thinking Framework
+
+#### Algorithms
+
+* Uses diagrams to express solutions.(AB)
+* Recognises that different algorithms exist for the same problem (AL) (GE)
+* Represents solutions using a structured notation (AL) (AB)
+*  Can identify similarities and differences in situations and can use these to solve problems (pattern recognition)(GE)
+
+#### Programming & Development
+
+* Creates programs that implement algorithms to achieve given goals (AL)
+* Selects the appropriate data types(AL) (AB
+
+#### Information Technology
+
+* Collects, organizes, and presents data and information in digital content (AB)
+* Makes appropriate improvements to solutions based on feedback received, and can comment on the success of the solution (EV)
+* Recognises ethical issues surrounding the application of information technology beyond school.
+
+Computational Thinking Concept: AB = Abstraction; DE = Decomposition; AL = Algorithmic Thinking; EV = Evaluation; GE = Generalisation
