electroblocks / electroblocks

This is an Arduino simulator that allows you to code with a drag and drop language called Blockly.

ElectroBlocks

So we are working on contributing docs. Right now everything is setup for people to add boards and their own libraries as well. I am working on what that process will look like and the documentation for that process. I will definitely be asking for a lot of help so if you have ideas please let me know.

NeoPixels Default Value

Neopixels needs a default value if no block is present.

Remove the Board Selector

Why

1. It has nothing to do with the coding of the app and can be put into setting
2. Adds noise to the overall process
3. Some boards like the micro bit will require a complete redoing of the Blockly toolbox
4. Switching boards is a scarce thing. Meaning most people will stick with one for a bit.

Delay block should add to the virtual time

Graphics Audit

Make sure all the graphics are labelled

Chrome 85

Chrome 85 does not work with the avrgirl-arduino library. Might take care of itself.

LiquidCrystal

• Add Liquid Crystal to server
• Modify the Generator Code
• Modify the wiring / virtual circuit

Might not do this one because I found an i2c convertor. That would make it work. It seems the breadboard connections would be really hard.

FastLED Custom Blocks Won't Generate Code

Hello!

As soon as I submitted my first issue, I realized where to look and fixed it.

Now my blocks show up in the drawer but the code will not populate in the code window.

Adding one of the custom blocks causes all other blocks to break as well.

Any thoughts?

I've included a picture of the problem and here is the code for my generators.ts file.

`import Blockly from 'blockly';
import _ from 'lodash';

Blockly['Arduino']['fastled_setup'] = function (block) {
const numberOfLeds = block.getFieldValue('NUMBER_LEDS');
const pin = block.getFieldValue('PIN');

Blockly['Arduino'].libraries_['define_fastled'] =
'#include <FastLed.h>;\n\n' +
'CRGB leds[NUM_LEDS];';
Blockly['Arduino'].setupCode_['fast_led'] = '\tFastLED.addLeds<WS2811, ' + pin + 'GRB>(leds, ' + numberOfLeds + ');';

return '';
};

Blockly['Arduino']['fastled_set_color'] = function (block) {
Blockly['Arduino'].functionNames_['set_color'] =
'\n\nvoid setNeoPixelColor(double pos, RGB color) {\n' +
'\tpos = pos <= 0 ? 0 : pos;\n' +
'\tpos = pos >= 1 ? pos - 1 : pos;\n' +
'\tpixels.setPixelColor((int)pos, color.red * brightness, color.green * brightness, color.blue * brightness);\n' +
'\tpixels.show();\n' +
'}\n';

let color = Blockly['Arduino'].valueToCode(
block,
'COLOR',
Blockly['Arduino'].ORDER_ATOMIC
);

if (_.isEmpty(color)) {
color = '{ 0, 0, 0 }';
}

const position = Blockly['Arduino'].valueToCode(
block,
'POSITION',
Blockly['Arduino'].ORDER_ATOMIC
);

return '\tsetNeoPixelColor(' + position + ',' + color + ');\n';
};
`

Fix RGB LED Wiring

The resistors should be connecting the other side of the breadboard.

Fix the chrome version dialog box issue

Non dynamic by number in the for loop

The forloop by number should not be dynamic. Consider making the whole loop nondynamic.

ElectroBlocks Code View

So the code view needs a margin-bottom: 10px on the pre element so that it can scroll all the way down.

LCD Screen and NeoPixels

Fix neopixels first led not working

FIx LCD Screen it's not showing letters

Fix Svg loading issue

Wait 20 milliseconds before calculating the height. Make sure it's not negative.

Create an LED Matrix Block with we going to add a color picker to it

Remove lodash

See if you can remove lodash with modern javascript.

Centering Bug

When you don't have any blocks and go from the Arduino page to the home page, it does not center properly.

Remove unnecessary code for digital display

Purpose

Remove the unnecessary code for the digital display. Notice the variable digitalDisplayPrint123 is not being used for anything.

int simple_loop_variable = 0;
struct RGB {
	int red;
	int green;
	int blue;
};

#include "SevenSegmentTM1637.h"
String digitalDisplayPrint123 = "";
const byte PIN_CLK = 11;   // define CLK pin (any digital pin)
const byte PIN_DIO = 10;   // define DIO pin (any digital pin)
SevenSegmentTM1637    digitalDisplay(PIN_CLK, PIN_DIO);





void setup() {
  digitalDisplay.begin();
    digitalDisplay.setBacklight(100);

}


void loop() {
  // Sets the text and turns the colons on and off.

    digitalDisplayPrint123 = String(" 100");
    for (int i = digitalDisplayPrint123.length(); i < 4; i += 1) {
      digitalDisplayPrint123 += " ";
    }
    digitalDisplay.clear();
    digitalDisplay.setColonOn(true);
    digitalDisplay.print(String(" 100"));

}

Add Auto Resizing

When a user resizes their window we should trigger a resize event.

When you add to a loop in for the sensor setup block there is an error

ElectroBlock Chrome Books Uploading Error

In chromebooks the API should be baudrate, not baudRate. It's erroring out on chrome books.

Default Wait Time .2 seconds

• Change the default wait time to .2 seconds.

Led Matrix Bug

It's assigning the wrong led number to the led matrix. We need to reverse the x and y and start at 0.

// x = 2, y = 3 parameter

LED Matrix still broken

Purpose

Get the led matrix working agian.

Create a self host environment option

Create a virtual environment that does not require the internet for people with bad internet. Nice to have would be able to make it deployable on the raspberry pi.

Create Documentation

Create Docs

• Adding Boards
• Adding Components
• Adding / Modifying blocks
• Tour of site
• Everything else

Sending Message Bug

Purpose

When sending a message you don't see the message that you sent appear on the screen. Should be an easy fix.

The virtual circuit needs to take up 1/2 the space at least

The virtual circuit is a star of the show and needs at least 1/2 the space.

Linux does not work

The serial API for Linux returns an array of ports and not a single one. I will need to investigate this more text time I can access a Linux box.

Starters

Starters

We need starters for electroblocks. Basically predone projects that just need a little bit of logic.

Easter Eggs

Hidden features in the code

Block Improvement

Add Blocks

• If Blocks should have if-then and remove the do from it. Like Scratch
• See if it's possible to put the for loop block in line.
• Add runs (x) Times in the virtual circuit to the loop block.

Not able to upload the program to arduino. Showing wait for 5 mins always.

RGB LED Fix

We need to make the resistors not be plugged in the same row as the wires they are connecting.

Fixing Scroll bar bug on older computers

There is a bug that does not show up on any of mac books and is where scrollbars are being added all over the place.

Figure out the "hook"

Come up with something that will really grab the student's interest.

Multiple List Bug

I should be able to select from the list of numbers when using get an item in list block or a set item in list block.

FastLED Add-On

Hello!

I love what you've created here. I was trying to do something similar then found this and thought it would be easier to implement a new add on than start from scratch.

I went through this process: https://github.com/ElectroBlocks/ElectroBlocks/blob/master/docs/how-to-create-a-component.md

I was able to get the project to run but only the category appears and the blocks won't populate.

Any ideas where to start looking or suggestions?

OLED Display

Create OLED component

Player on home page does not stop going when you navigate to another page.

Create show neopixel block and remove that from the set new-pixel block

This will led colors will not change on the simulator until show is called

Navigation Bar doesn't load right

What happening is that Blockly is taking up more space because of the scroll bar at the bottom. Need to ad some more height to it. It seems happen when you load a starter page.

This happens on load for the page:

https://sfl-electroblocks.web.app/?lessonId=xbtqlYmbDV65Cwe7ncs7

Test should run on every pr

Tests should run on every pr.

Will use travis cli and codecoverage

ESP8266 Chip

It would be amazing to get this chip working with ElectroBlocks. I think we only need a few versions of the chip. If we can flash online that may be the way to go.

LED Resistor

Fix the led resistor that it plugs into ground and not into the same row.
