• Hat Block or Event Block is used to start the script and is always placed on top of other blocks.
• Stack Block is a rectangular block that can fit other blocks above or below them. This is used to get the key commands executed.
• Looks Block is for a display character with LED matrix.
• Show Block is for turning on the LED lights and playing sounds.
• Action Block is for the DC motor movements.
• Control Block is for executing command action from the script.
• Sensing Block is for executing the command for sensor.
• Reporter Blocks contain a value that can be a numerical value or character string. These can be used in any script that requires data but cannot be used independently. It is typically located at the operators block and sensing block.
• Boolean Blocks contain a condition which can be either "true" or "false". It is typically located at the operators block and sensing block.
• Cap Block ends a script or a project. It can only be placed under all the other blocks.
• A sensor is an input device that responds to its physical environment with specific inputs like pressure, moisture, light, heat, motion, and other phenomena.
• Ultrasonic Sensing is a technology used to survive in any lighting environment while avoiding a robot colliding with other objects. It has greater accuracy than other methods in measuring the thickness and depth of parallel surfaces.
• An Ultrasonic Sensor is a type of sensor that uses ultrasonic sound waves to measure the distance to an object. It can easily detect external or deep objects with its high frequency, high sensitivity, and high penetrating power.
