Medicines are an essential part of our lives since they help us stay healthy, prevent illnesses, and treat disorders. This role is extended during current times, where many diseases are a broad concern, and remembering or forgetting to take a medicine could result in the difference between life and death. As such, it is essential to pay attention to the daily doses of patients and the daily doses of the ones we love. This paper suggests a solution to this problem in the form of an automatic medicine dispenser that is easily controllable through a mobile application. The major components of this medicine dispenser are Light emitting diodes or LED's, a buzzer and an Esp8266 Node MCU (Microcontroller Unit) wi-fi module, which enables the hardware and software to be connected through wi-fi. The design includes two different indicators, the light indicator, in the form of a Light Emitting Diode (LED) meant for the deaf and the sound indicator in the form of a buzzer as an indication to the blind. Once the user gets their pill, the indicators will be reset until it's time to take the medicine again. The design of this product ensures that the timing and the quantity of tablets to be taken can be administered using a mobile app, making things convenient and easy for everyone involved. Furthermore, the device will also be greatly beneficial in hospitals by taking a load off the medical staff during these hectic days. The device is simple and cost effective and the software is sturdy and reliable. [ABSTRACT FROM AUTHOR]

In recent years, portable electronic devices such as gadgets, tablets, mp3 players grow rapidly as daily devices for supporting people activities. In many applications, portable electronic devices need power backup. Since wireless power technology has been introduced in mobile device applications, portable power backup has become more popular to extend the battery life of mobile devices, moreover, the power backup technique also can utilize the advantages of wireless power technology. This paper presents the development of a dual-mode power bank: wireline and wireless, especially for gadget device power charge applications, to enhance user experience. The power backup is stored in a Li-ion rechargeable battery where the power in-outlet is monitored by the power monitoring module. The developed device was designed in a compact, simple, and portable module in the fashionable casing regarding the wireless power bank device. Concerning the wireless system, it was also designed based on Qi-standard Wireless Power Consortium (WPC), working at an operating frequency of 110kHz, maximum transmission distance at 10mm, and providing power at 5W. Experimental and validation reveal that the device can provide power 5V at maximum current 1A. The power transfer efficiency is around 70% and compatible with Qi-standard wireless power charger either modular or built-in inside portable electronic devices. [ABSTRACT FROM AUTHOR]

Internet of Things (IoT) technology can connect various household devices through the internet network. This technology can help to monitor and control devices in the home, so efficiency can occur. This paper discusses the design of a smartphone-based application that can control television via the internet, so that it can be controlled even if the user is not in the TV room. This system uses a NodeMCU microcontroller to control infrared-based TV remotes. In addition, NodeMCU can decode real-time Firebase databases connected to smartphone applications programmed by using the Flutter framework. The developed application has a function that resembles the function of a TV remote in general. In addition to having commands such as a TV remote, the application also has additional features such as: "go to channel", "turn off timer", and "volume preset". Commands given through the UI of the app are stored in Firebase. The NodeMCU executes the command and transmits it with an infrared signal. The command is in the form of a Boolean variable. The test results show that the system can execute every command from the HP with an average execution time of 880 milliseconds. [ABSTRACT FROM AUTHOR]

In a huge congregation, several pilgrimages went missing because they got lost or other causes. Moreover, during the holy seasons, cases like panicking due to getting scattered around from the group or getting lost and not finding the way back. To accommodate this problem, Portable Pilgrim Tracker is proposed in this paper to overcome those missing pilgrimages cases. Portable Pilgrim Tracker is a monitoring and tracking device designated to detect the user's location and heart rate in real-time. Using Wi-Fi technology as the medium of data transmission, the data is collected from the GPS module and pulse sensor Arduino. The information such as the user's real-time location and heart rate will be sent to the guardian's Blynk mobile application. With the usage of this portable pilgrim tracker, it is expected that this will be able to assist the mobile application user (guardians or travel agency staff) with the screen of live maps about Pilgrim's location and their heart rate to avoid any unwanted consequences such as missing Pilgrim and health compilation.
