Lets do connections.<br/> <br/> You can follow teachers instructions or check connections from the screen:<br/> Remember that LEDs long leg goes to + and short leg goes to ground!<br/> <br/> <br/> <a href="https://peda.net/p/ville.eronen/robotics-and-coding/nimet%C3%B6n-0241/led-ja-vastus-jpg3#top" title="LED ja vastus.jpg"><img src="https://peda.net/p/ville.eronen/robotics-and-coding/nimet%C3%B6n-0241/led-ja-vastus-jpg3:file/photo/f40c12e9e11ca201b8d56901c5c6e16ef5d70e23/LED%20ja%20vastus.jpg" alt="" title="LED ja vastus.jpg" class="inline" loading="lazy"/></a><br/> <br/> <br/> <br/> 2. Lets do the code<br/> <br/> <a href="https://peda.net/p/ville.eronen/robotics-and-coding/nimet%C3%B6n-0241/light1-png2#top" title="light1.png"><img src="https://peda.net/p/ville.eronen/robotics-and-coding/nimet%C3%B6n-0241/light1-png2:file/photo/cc5d330240b7023aa50aeec2977d8633d7260593/light1.png" alt="" title="light1.png" class="inline" loading="lazy"/></a><br/> <br/> We still need to think good level for lighting to shut down LED<br/> <br/> 3. Lets find out what light level we have when lights in the classroom are ON and when lights are OFF<br/> <br/> Example<br/> <table border="1"> <tbody> <tr> <td> </td> <td>Light level</td> </tr> <tr> <td>Light On</td> <td>100</td> </tr> <tr> <td>Lights Off</td> <td>30</td> </tr> </tbody> </table> <br/> -&gt; We will choose light level around 60 2019-06-26T07:36:47+03:00
