Mikrokontrolieru programmēšanas iespējas un pielietojumi
2016
Mūsdienās mikrokontrolieru vadītām ierīcēm ir liela nozīme. Pastāvīgi pieaug pieprasījums pēc lietojumiem, kurus ir nepieciešams vai ir vēlams automatizēt un mikrokontrolieri ir tieši paredzēti tam. Šajā darbā tiek apskatīta mikrokontrolieru uzbūve un apkopoti to pielietojumi mūsdienās. Kā arī apskatīta Arduino mikrokontrolieru prototipēšanas platforma. Pētījuma rezultātā tika izveidots ierīces prototips uz Arduino mikrokontrolieru prototipēšanas platformas bāzes.
Photovoltaic plant array reconfiguration: Design of a new device
2014
An efficient strategy to improve unequally irradiated PV plants performances is based on the reconfiguration of the connections between the modules. In this paper, an algorithm, for this purpose conceived, is presented. Moreover, the design, realization and finally also the set up of a new reconfiguration system device is fully shown and discussed. The algorithm conceived simulates several possible series-parallel connections under varying irradiation conditions, and determines the optimal modules connection in order to get the maximum output power. In this way, the reconfiguration system may set up the reconfiguration strategy. The reconfiguration system prototype set up, basically consist…
Piezoelectric Rainfall Energy Harvester Performance by an Advanced Arduino-Based Measuring System
2018
This paper presents the performances of rainfall energy harvesting through the use of a piezoelectric transducer and an Arduino-based measuring system. Different studies agree on the possibility of generating electricity from rainfall, but to date, a study on measuring the quantity of energy produced during rainfall is still missing. The present study begins with results obtained from laboratory researchers using piezoelectric transducers and oscilloscopes, finalized to measure the energy produced from a single raindrop, and concludes with an ad hoc Arduino-based measuring system, aimed to measure the actual amount of electrical energy produced by a piezoelectric transducer that is exposed …
Automated single ring infiltrometer with a low-cost microcontroller circuit
2015
Automation of a new single ring infiltrometer.Data acquisition system based on the open source microcontroller platform Arduino.New method to minimize the disturbance of the soil surface.New approach to process transducer output. A method to automate data collection with a compact infiltrometer under constant head conditions was developed. The infiltrometer consists of a containment ring with a small quasi-constant head of water (i.e., 2-3mm) that is controlled by a Mariotte reservoir and a data acquisition system based on the open source microcontroller platform Arduino and a differential pressure transducer. The presented design can be easily reproduced and operated.The infiltrometer was …
L’Aula Magna dell'Università di Palermo: cronistoria di un cantiere decorativo (1928-1938)
2020
Situata all'interno dell'odierno Dipartimento di Giurisprudenza, l'Aula Magna dell'Università di Palermo è stata progettata dall'architetto Antonio Zanca che firma nel 1929 il progetto esecutivo di un ambiente neo-settecentesco dotato di mobilio e decorazioni pittoriche sulle pareti. Nel 1934 è stato indetto un concorso nazionale per l'affidamento delle decorazioni pittoriche vinto da Arduino Angelucci e Manlio Giarrizzo cui spettano rispettivamente la volta e le pareti. Grazie alla stampa locale è possibile ricostruire - almeno in parte - le vicende di questo concorso che si colloca in un contesto nazionale fortemente attento, dopo la Triennale di Milano del 1933, al problema della decoraz…
Robotized semiautomatic motorcycle transmission development. Electronic and software design
2017
In this paper, we propose an electrical design (implemented on a PCB board) and an accompanying software design for controlling the automatic gear change. The designs complement the mechanical solutions developed in Part 1. The paper also analyses the issues encountered during the intermediate steps of the development of the electronic module, which is expected to be small and adaptable enough to be installed on a motorcycle without changing its ergonomics. The control software runs on the Arduino Nano board and is built as a state machine with one idle state, five active states that cover different stages of the gear change and one error state for preventing malfunctions in case of an unex…
Creating an ethernet communication between a Simatic S7-1200 PLC and Arduino Mega for an omnidirectional mobile platform and industrial equipment
2020
Abstract The degree of automation in the industry increases more and more every year, trying to reduce more and more or even eliminate the collaboration with the human operator. The basis of all automatic industrial equipment is PLCs. This paper presents a method of extending the number of inputs and outputs of a Siemens Simatic S7-1200 PLC, using an Arduino Mega development board and an Ethernet communication. Following the realization of this communication, the number of inputs and outputs will increase considerably, being able to connect various sensors used for the construction of an omnidirectional mobile platform, but also for equipment for industry. The advantages of using this commu…
Robot Retrofitting by Using LinuxCNC Complemented with Arduino/RaspberryPI
2020
The use of robots for any manufacturing process is present in almost every industry nowadays. Nevertheless, automating the manufacturing process has always been a challenge for every one of them due to costs and complexity of adding this kind of automation. Acquiring robotic equipment in a concentrated market where the vendors have locked-in their clients can be expensive. In addition to this, the development of intern-factory made solutions has a very steep learning curve and it is not easily achievable. Due to these barriers small and medium size players can’t easily jump into this revolution.

Pašbraucošu automašīnu algoritmu testēšanas iespējas autosacīkšu simulatoros
2020
Dažādi autovadītāju asistenti arvien vairāk iesaistās automašīnu vadīšanā. Pamazām parādās arī iebūvēti autopiloti, taču radīt pašbraucošas mašīnas ir ļoti dārgi un sarežģīti. Darbā tiks pētīts, kādus pašbraucošu automašīnu algoritmus un tehnoloģijas ir iespējams attīstīt uz autosacīkšu simulatoriem, izmantojot modificētas datora perifērijas ierīces un mikrokontrolierus. Algoritmu mērķis ir ne vien korekti veikt noteiktu maršrutu, bet arī spēt to izdarīt pēc iespējas ātrāk, maksimāli maz atpaliekot no cilvēka vadīta transporta. Algoritmus realizēs izmantojot mikrokontrolierus, kas pados signālus specializētām datorspēļu perifērijas ierīcēm, kas ar datoru sazināsies kā parasts datorspēļu kon…
