How to use the Evive Terminal Module

Example Description
The evive Terminal Module in PictoBlox enables two-way communication between the evive device and the Dabble app using Bluetooth. Through the Terminal Module, users can send text commands or numeric values from a smartphone to control hardware components such as LEDs, motors, and relays. It can also transmit sensor readings and status messages from evive back to the smartphone in real time.

Introduction

This module provides a simple and interactive way to understand wireless communication and data exchange in embedded systems. With the Terminal Module, learners can build a variety of projects such as LED and motor control systems, sensor monitoring applications, data logging systems, and smart automation solutions. It is an excellent tool for introducing students to the fundamentals of the Internet of Things (IoT), Bluetooth communication, and command-based programming through hands-on activities. 

Prerequisites 

  1. Evive device (powered on)
  2. USB cable for connecting Evive
  3. PictoBlox installed on your computer
  4. Basic understanding of block coding
  5. Note: Before connecting Evive to PictoBlox, ensure that the Arduino/CH340 device driver is installed properly. 

Connecting Evive to PictoBlox

  1. First, open PictoBlox.
  2. Then, connect Evive to your computer via a USB cable.

  6. Since we’re going to work in Stage mode, we must upload the firmware to the board. It will ensure real-time communication between the board and the computer. Uploading the firmware is a one-time process. To do so, click on the Upload Firmware button. Observe that while doing so, the Rx0/Tx0 LED starts blinking.

To check whether the firmware has successfully been uploaded or not observe evive’s screen. If evive’s logo appears on the screen, it indicates success. Otherwise, retry the process.

Step-by-Step Block Coding Guide

We will use the set digital pin () output as () block to turn the LED ON/OFF.
