Code
1. Drag two basic blocks.
2. Drag an "if else" block, and fill the hexagon with a item100 block. Set the value to "read the value of sound
IO33". If the condition is satisfied, LED outputs a HIGH level at pin IO25 with a delay of 2s; or else, it outputs
a LOW level at the same pin without a delay.
