Important update – In June 2023 LEGO decided to update the Powered Up app with a new code block design, and in July they provided their own block guide that is accessible here. Their page has the most frequent blocks described, and you can find a link on that page with a pdf that has all the new blocks. The guide below is useable with the 3.x.x version of the app.
This is the full code block guide for the LEGO® Powered Up app.
Latest update: 04/29/2020
App version used: 3.1.1
Usage
This is the extended version of the code block guide. Click here for the simple version with an easy navigation interface.
In this version you have the following options:
– filter columns – use the Column visibility button to toggle the columns
– search – use the search text box to filter for any expression (e.g. block category)
– change the number of rows – use the Show x entries drop down to change the rows displayed. Only advised to increase on a touch screen interface where the table can be scrolled horizontally without the slider on the bottom.
Glossary
Simple motor – a Powered Up motor that only has power regulation, like the 45303 Simple Medium Linear Motor
Tacho motor – a Powered Up motor that has an internal encoder and has speed and position regulation like the 88008 Medium Linear Motor or the L / XL motors.
Slider interface – one of the controller interfaces in the Free Code area of the Powered Up app with 2 sliders and 3 buttons
Race Car interface – one of the controller intarfaces in the Free Code area of the Powered Up app with 1 joystick and 4 buttons
Composite Block – a block that contains one or more program sequences
Disclaimer – This guide is partially based on a document received from LEGO® Customer Service, additional information and examples were added based on the Powered Up app and my experience.
| Block Image | Block Category | Block SubCategory | Block Name | Description (official / my notes) | easy | medium | hard | App version | Example | Example (code) | Notes |
|---|---|---|---|---|---|---|---|---|---|---|---|
 | Flow Blocks | Start | Starts the execution of the attached sequence when the block is clicked or when the program starts. | x | x | x | 2.1.0+ | Starts the sequence that sets the motor power on port A to 50 |  | ||
 | Flow Blocks | StartOnTrue | Starts the execution of the attached sequence when the condition is true. | x | x | 2.1.0+ | If Slider 1's position is not 0 then sets the light intensity on port D to 100% |  | |||
 | Flow Blocks | StartOnEdge | Starts the execution of the attached sequence when the condition switches from false to true. | x | 2.1.0+ | If Slider 1's position is changed from 0 then play the car start sound |  | ||||
 | Flow Blocks | EventStart | Starts the execution of the attached sequence when the flag number is triggered. | x | x | 2.1.0+ | The Start sequence begins first, sets the light intensity on port D to 100% then triggers the "Flag 1" sequence that sets the motor power on port A to 50. |  | |||
 | Flow Blocks | EventTrigger | Triggers flag number. | x | x | 2.1.0+ | The Start sequence begins first, sets the light intensity on port D to 100% then triggers the "Flag 1" sequence that sets the motor power on port A to 50. |  | |||

 | Light & Sound | IR | SendIRMessage | Sends IR commands to the Power Functions IR reciever with the Color and Distance sensor connected to the port defined.The first parameter is the port where the sensor is attached. The second is the IR channel used from 0 to 3 matching IR port 1 to 4. The third defines multiple things, but for basic usage set 4 to control the red port, 5 to control the blue port. The fourth sets the speed, 0 is float (no speed), 1 to 7 is increasing speed forward, 8 is stop, 9 to F is decreasing speed backwards. | x | 3.1.0+ | The first block sets the Color and Distance sensor attached to port A to mode 7 to transmit IR signals, that is needed before sending the commands.
