Antarmuka Mikrokontroller IoT (ESP32) Dengan USB Host max3421e

Electronic equipment made using old technology or electronic equipment in the entry-level category has not been supported by networking equipment, so for the data communication process, the microcontroller requires interfacing facilities that are in accordance with the electronic equipment used, such as a USB port. With the microcontroller that supports IoT, it allows electronic equipment to communicate over the network. An IoT microcontroller such as the ESP32 is equipped with a WiFi feature but is not equipped with a USB controller feature, while the USB Host max3421e supports the communication process using SPI, so that those two microcontrollers can be used to form an interface using the SPI bus. This interface can be applied to electronic equipment with old technology and entry level electronic equipment for wireless communication. For the needs of making an interface between the ESP32 and max3421e, a software was developed by analyzing the SPI features of the ESP32 and the USB protocol according to the USB device state diagram. The results obtained are the handshake process between systems developed with USB devices in the Low-Speed ​​and Full-Speed ​​categories such as printers, flashdisk, bluetooth mouse and external hard disk, and the device descriptor data of each device tested can be read properly.

Development of robotic rover with controller & vision system

<p><span>Rover is a robotic system that integrates a simple system implementing electrical and mechanical components together. In this study, we propose a rover using mechanical components which consist of a robotic arm, joint and mechanical gripper, backbone chassis and continues track, while the electrical components include servo motor, servo controller, transmitter and receiver for vision system and wireless controller via USB host as its control system. The purpose of this project is for monitoring and safety purposes. In addition, the main goal of this project is to develop a simple robotic rover that is easy to build and manufacture as well as cost-effective. To add more functionality on this rover, it is equipped with a robotic arm and real-time view camera integration. This rover is equipped with a first-person view (FPV) camera, an integrated camera on the rover that can give clear visibility and direction to the rover pilot. The live feed can be viewed on the monitor inside the command station box. It can be used to assist safety authorities to collect information &amp; insights, work lift to collect and remove the load and to conduct search and rescue operation. As for the result, the mobility system of the robotic rover at terrain surfaces and analyses the capabilities of the chassis during lifting load had been tested.</span></p>

Perancangan Pengontrolan Overhead Crane Menggunakan Kabel dan Nirkabel Berbasis Arduino

Overhead Crane is a heavy equipment which is very much found in various industries, factories, and workshops that are used to transport material. In general, controlling the Overhead Crane is operated by using a Push Button that is hung together with a cable on the top frame of the Overhead Crane. in this case, humans must also be able to maintain a distance when controlling Overhead Cranes that are working to transport memterials to avoid the use of Overhead Cranes. To provide security and comfort in the use of Overhead Cranes, the authors designed an Overhead Crane controller using Arduino based cable and wireless. The design of Overhead Crane control using a cable consists of several series of Push Button arranged in a plastic box and then hung on the side of the Girder Crane. for the input foot the Push Button is given a voltage 12 VDC, while the output of the Push Button is connected with contact points of the Relay 12 VDC to execute electrically mechanical Overhead Crane. While the Overhead Crane control design using wireless consists of several components, including: Arduino Mega 2560 which is combined with USB Host Shield. Bluetooth csr 4.0 Dongle is connected to the USB Host Shield port for data communication media between Arduino Mega 2560 with Bluetooth Joystick PlayStation 3 (PS3). The signal pin of the Relay modules is connected with Arduino Mega 2560 pins according to the program designed. Contact NO points Relay modules are connected with 12 VDC Relay point contacts to execute electrical mechanical Overhead Crane.

KONEKSI JARINGAN ANTARA DUA KOMPUTER MENGGUNAKAN KABEL USB NETWORK/BRIDGE DENGAN CHIP BRIDGE PL 2501

Koneksi jaringan ini berisi tentang membangun jaringan sederhana antara dua buah komputer tanpa menggunakan ethernet card melalui port USB. Permasalahan yang muncul adalah sistem USB didesain hanya untuk berkomunikasi dengan peralatan USB, sehingga antara USB Host Controller pada sebuah komputer tidak dapat secara langsung terkoneksi dengan USB Host Controller pada komputer lainnya. Dengan menggunakan kabel USB Network/Bridge sebagai peralatan USB, maka USB Host Controller dapat saling berkomunikasi. Kabel USB Network/Bridge ini memiliki rangkaian elektronik yang berfungsi sebagai pengatur lalu lintas data dari USB Host Controller pada komputer A ke USB Host Controller pada komputer B maupun sebaliknya. Sehingga dalam membangun jaringan melalui port USB diperlukan peralatan USB sebagai media komunikasi antara Host Controller.
