Using BLOX to build firmware is like piecing together a puzzle where each piece represents a different action or decision your device needs to make. Here’s a simple way to understand it:

Everything Happens Sequentially:

• Imagine you're giving instructions to a robot. You tell it to move forward, then turn left, then pick up an object. The robot will follow these steps one after another, in the exact order you gave them.
• In BLOX, each block you place in the workspace is like an instruction for your device, and it will follow these steps in the order they appear.

Logic Flow Control:

• Inside this sequence, you may sometimes want your robot to repeat a task, like picking up 10 objects one by one. Instead of giving the same instruction 10 times, you can use a Repeat Block.
• A “repeat” block tells the robot, “Do this task a certain number of times,” while a “while” block tells it, “Keep doing this task as long as a certain condition is true.”
• Sometimes, you want your robot to make decisions. For example, “If there's an object in front of you, pick it up; if not, keep moving.”
• In Blockly, you can use logic blocks like “if” to control what your robot does based on different conditions. This way, you can make your device smart enough to handle different situations automatically.
• If you'd like the device the wait, you can use a Delay block
• There are many more examples

By arranging these blocks in the workspace, you're essentially building a set of instructions that the firmware will follow, making your device do exactly what you want it to do.

To demonstrate this, lets start with a very basic example.

Your BLOX has two onboard RGB LEDs. Let's setup a simple program to control these LEDs.

Once it starts to run the firmware we want to:	If we build this out in BLOX it would look like this:
- Set both LEDs to RED - Wait for 1 second - Set both LEDs to GREEN - wait for 1 second - Set both LEDs to BLUE - wait for 1 second - Then repeat (the pattern will run over and over)
