Coding the streetlight using the volume sensor

Do you remember how you coded the streetlight using the brightness sensor?

Now, we are going to use the volume sensor to code the streetlight. Since we learned how to turn on and off the

streetlight, now we are going to make a streetlight that changes its brightness depending on the analog value.

We used the ‘digital output/off’ block to turn the LED sensor on and off. For the analog value ouput, let’s see which

block we should use. Drag in the block below to the script.

Did you drag in the block from the movement tab? Ompared to the ‘digital output/off’ block this block shows the

output value in numbers. Basically, it can control the brightness by typing in the output value.

Let’s use the streetlight here. We should connect the volume sensor instead of the brightness sensor. Connect the

brightness sensor to analog input port 0 (port 1) and the LED sensor to analog output port 9 (port 17).
