So Smart Trashbin is a project that requires us to create coding with blocks in pictoblox, pictoblox is very similar to scratch or turbowarp but pictoblox has a lot of features, it can even code microbit and others, one of which is arduino, arduino has many types for example there are arduino mega, arduino nano, and arduino uno, for Smart Trashbin we use arduino uno, we use pictoblox to code arduino uno which will be used to move the trash can lid so that it can move when the ultrasonic sensor detects something in front of it,
