Use Push Buttons on your Magicbit [Magicblocks]

Hello and Welcome, This short tutorial will teach you to Control a motor by a Magicbit using Magicblocks.

There are 1 main methods of achieving this goal;

• By using Dashboard Text.

First of all log into to your Magicblocks account,

Magicblocks is an easy visual programming software for program your magicbit. Anyone can program their micro controller by using magicblocks.io and there is no need of programming knowledge. You can sign up for free.

Start and Open the Playground.

Next make sure your Magicbit is connected to the internet and plugged-in and also linked to your account through Device Manager.

All Done? then scroll down to Method 1

List of Items Required

Magicbit: Magicbit is an integrated development platform based on ESP32 for learning, prototyping, coding, electronics, robotics, IoT and solution designing.

Setting Up the Digital In Block

1. Drag & drop the Digital In block from the input nodes section on the left of the screen to the Flow.

2. Double-click on the Digital In block and type or paste your unique Device id from the Device Manager Tab on your Magicblocks account. [ This will link the digital in with the Magicbit ]

3. Choose 'PB Right(34)' or 'PB Left(35)' from the PIN drop-down menu.(Connects with the Right or Left Push Button on your Magicbit)

4. Select the Method as Interrupt from the drop-down menu.

Setup the Change Block

(This Node is used to change the 1 & 0 signal input from the Digital In node to any text you want)

1. Drag & Drop the Change Block from the function nodes section on the left of the screen to the flow.

2. Add new rule from the '+' Button to use 2 rules.

3. Change the function of both of the rules from Set to Change from the drop-down menu.

4. Next change the 'Search for' function from String(text) to Number in both of the rules. And make sure the 'Replace with' function is set to String(text).

5. Set up the rules.

• The First Rule to search for '1' in signal input and replace it with our text (e.g. 'Right Button Released' or 'Right OFF')
• The Second Rule to search for '0' in signal input and replace it with our text (e.g. 'Right Button Pressed' or 'Right ON')

the text 'Right' or 'Left' depends on the Push Button which is linked to the Digital In Node in the above step.

(image below shows an example of the rules)

Setup the Text Block

1. Drag & drop the Text block from the dashboard nodes section to the Flow.

2. Double-click on the text node and set up a basic dashboard ui [user- interface] from the drop-down menu and a name for your field.

[Optional] Setup the same node configuration for the other Push Button

1. Copy & Paste the 3 nodes.

2. Change the PIN on the Digital In node for the other Push Button.

3. Change the Text in Change node from 'Right' to 'Left' or vice versa.

[Optional] Import Already Setup Nodes

If you had trouble setting up nodes, you can use the import feature in Magicblocks to get the nodes which has been already setup.

• First copy this code to your clipboard;
