Use Ultrasonic Sensor With Magicbit [Magicblocks]

This tutorial will teach you to use the Ultrasonic Sensor with your Magicbit using Magicblocks. We are using magicbit as the development board in this project which is based on ESP32. Therefore any ESP32 development board can be used in this project.

• Magicbit - Pro

Hello and Welcome, This short tutorial will teach you to use Ultrasonic sensor with your Magicbit using Magicblocks.

There are 1 main method of achieving this goal;

• By using Dashboard Gauge.

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
