A method for feedback delay measurement using a low-cost Arduino microcontroller: Lesson learned: Delay influenced by video bitrate and game-level

The Automated Teller Machines (ATM) are used for cash withdrawals. Meanwhile as ATM lacks security, thefts occurring in the ATMs are also high. Our proposed system minimizes those break-ins occurring in the ATM’s by instigating a low cost standalone embedded sys-tem using Arduino Microcontroller. This system is proposed for ATM security, comprising of the components namely RGB tag, Global System for Mobile communication (GSM), Global Positioning System (GPS), Virtual Keyboard and camera. Authentication by virtual keyboard thus helps the public to protect their credentials from being captured by malicious bots, key loggers and spyware. Whenever theft occurs, Buzzer makes an alarm, DC Motor turns ON and the door of ATM is closed. The nearby police station and corresponding bank authorities is alerted by the GSM Modem that sends messages along with the location. This will prevent the robberies and the person in-volving in the robbery can be easily caught. In short, it discusses the methods that are used to detect the venture, initiate preemptive measures and forewarn the officials through GSM network. This system thus heightens the safety of ATM users as well as the ATM’s against forthcoming attacks effectively.

The Cost

Cardiopulmonary resuscitation method is used to save more number of peoples from the neurological problem. In this case, the neurological problem denotes brain death. This brain death is mainly caused due to cardiac arrest and happen within 4 to 5 minutes. To avoid this problem we go for cardiopulmonary resuscitation method. It will be helpful to relieve the patient from cardiac arrest. The manual CPR is not that much efficient when compared to automatic CPR because, the experts who are giving CPR to the patient are cannot able to give the continuous CPR to the patient but, the automatic CPR machine is able to give the continuous CPR to the patient. The article reviews such kind of automatic devices. The automatic CPR machine already exists. But, the cost of that machine is high. So we intended to design the low cost CPR machine. This is achieved by replacing the component like Arduino microcontroller and solenoid lock. The replaced component also do the same work like in the high cost CPR machine

The paper presents the results of a study with temperature measurements using low cost sensors connected to an Arduino microcontroller. To perform the study, three sensors widely used for monitoring environmental conditions with Arduino. The selected sensors were the LM35DZ (analog sensor) and DHT11 and DHT22 (digital sensors). The LM35DZ sensor is a sensor known to be an analog sensor that has linear temperature response with voltage. The DHT11 sensor measures temperature and humidity simultaneously. To measure temperature the DHT11 sensor uses a temperature-sensitive resistor and has a measurement range from 0 to 50 °C, with an uncertainty ± 2% ° C. The DHT22 has a measurement range -40 to 80 ° C and an uncertainty ± 1% ° C. Simultaneous temperature measurements with the three sensors showed good performance in indoor situations, showing the maximum and minimum temperatures of a daily temperature cycle.

Abstract The paper is to present a case study where different methods of programming are utilized by Mechanical Engineering Students to design a device. The objective is to provoke discussion and explore best practices on teaching Mechanical Engineering students the programming aspects. The task is to design a low-cost device that can accurately measure the period of a simple pendulum. Same raw materials, infrared break beam sensor and Arduino microcontroller, are given. But different programming approaches can be undertaken. Option 1 is to use C language and Arduino’s free Integrated Development Environment. Option 2 is to use Simulink with Arduino Support. Student survey is designed based on whether it is intuitive, whether it is easier to debug, etc. Further studies can be conducted to understand the effectiveness of a mixture of these different methods and sequence of exposure to these different methods.

Abstract Background Simulation training has become a core component in the training of ENT surgeons. It provides the opportunity for the repetitive practice of a surgical technique. Simulators are broadly categorised into low- and high-fidelity simulators. A method using a home microprocessor to enhance a low-fidelity surgical simulator is introduced. Method The Yorick tonsil tie trainer was enhanced using an Arduino microcontroller attached to the simulated inferior pole of the tonsil. The Arduino was coded to give a visual stimulus when linear motion exceeded parameters. The prototype simulator was tested to gain information on whether the enhancement could identify differences between novice and expert users. Conclusion An enhanced low-fidelity tonsil trainer was produced using a low-cost, simple home microprocessing board. The enhanced simulator gives objective feedback allowing for self-directed learning. Further research is required to evaluate the benefits of these enhancements above non-enhanced simulation training.

Nowadays, engineers are widely using accelerometers to record the vibration of structures for structural verification purposes. The main obstacle for using these data acquisition systems is their high cost, which limits its use to unique structures with a relatively high structural health monitoring budget. In this paper, a Cost Hyper-Efficient Arduino Product (CHEAP) has been developed to accurately measure structural accelerations. CHEAP is a system that is composed of five low-cost accelerometers that are connected to an Arduino microcontroller as their data acquisition system. Test results show that CHEAP not only has a significantly lower price (14 times cheaper in the worst-case scenario) compared with other systems used for comparison but also shows better accuracy on low frequencies for low acceleration amplitudes. Moreover, the final output results of Fast Fourier Transformation (FFT) assessments showed a better observable resolution for CHEAP than the studied control systems.
