NodeMCU merupakan sebuah papan mikrokontroler yang berbasis modul WiFi ESP8266, sehingga sesuai untuk diterapkan di bidang Internet of Things (IoT), smart home control atau aplikasi pengendalian tanpa kabel lainnya.   Para pemula tidak perlu kuatir untuk belajar mikrokontroler ini, karena pemrogramannya dilakukan seperti halnya pada Arduino.  Selain itu sudah banyak juga library yang beredar di internet, sehingga urusan pemrograman bisa lebih cepat.

In this article I like to share our experience about mobile robot project using Raspberry Pi as a main controller. Raspberry Pi is one of the popular mainboard recently as it is small, cheap and rich a lot of feature. Because of these reasons, I like to use it to control mobile robot, in this case we use mechanical robot platform from Vex. Objective of this project is to build pick and place mobile robot using image processing. We use PiCamera board to capture image and then process it using OpenCV library installed on Raspberry Pi.


GPRS communication with Arduino and SIM300 DZ

Today I would like to share my experience about Arduino which communicates with GSM/GPRS module, SIM300 DZ from SIMCOM.   Before I start, let me explain the goal of this project.  I want to bring some values or conditions from sensor to the internet, particularly social media like Twitter, Facebook or other website.


Sensors and some LEDs are connected to digital input/output in Arduino board.  For GPRS communication, SIM300 module is connected to RX, TX, and Ground.  Note that SIM300 works with 3.3 Volt DC and Arduino Mega 2560 works in voltage 5V.  Thus, transmit (TX) pin from SIM300 cannot be sufficient to deliver the logic to receive (RX) pin at Mega 2560, so we have to raise the voltage.  I use a pull-up resistor and it works successfully.

It's good to be considered that SBC may be used for your mobile robot project, instead of medium microcontroller like PIC or Atmega. Microcontrollers are also well and pretty fast in such application, but we are trying to look from another point of view.  Single board computer can handle multiple processes at the same time. Of course, it depends on operating system you are using.  More over, today's SBC has more powerful processor and more compact design.  We will talk about mobile robot application with medium size, about 30cm wide or length.
