This project aims to develop RFID reader. With the following scope can scan at least 15 cards save both entry and exit data display Welcome on the screen and add or reduce codes by yourself The test results show that the RFID scanner can scan both key cards and manually scan both in and out. The screen also shows Welcome when someone enters and shows thank you when someone shows that the developed scanner can be applied really slowly

Water became an important factor for propelling production process of any industries or factories and groundwater was option for production cost reduction especially in areas where had no surfacewater. B.Foods Product International Company Limited an affiliate of Betagro Group was located in Lop Buri Province to daily consume huge quantity of groundwater for production process in its factory. Measuring and recording levels of groundwater in 2 ground tanks related to volume of the water at time point of every 3 hours must continually be done every day in order to prevent lack of water fed into the factory that may impact of its production process. The main problem was caused of unexpected non-working of pumps. Knowing fluctuation of water levels could provide their immediate improvement and recover to avoid serious impacts. A microcontroller board could be employed to control groundwater volume in order that the company could closely follow up levels of groundwater in the ground tanks in real time and continuity. This study went on designing the microcontroller board for managing utility system and maintenance by using with level meter and wireless receiver and transmitter for testing working efficiency every 3 hours of each everyday during 1 February 2016 till 11 March 2016 totally 40 days. It was compared with those of same duration done manually. The findings revealed that the figured from 2 methods became similar and had very close relationship with each other. This could indicate that the simulated microcontroller board could be employed to automatically control groundwater volume efficiently. The company could bring it to appropriately trace levels of groundwater in the tanks in accordance with water usage behavior in each period of time for disruption of production process caused of insufficient quantity of groundwater. And this could be adaptable benefits for improvement of any organizations and also for any further studies

This paper aims to present a basic experimental microcontroller board for use in teaching the microcontroller and programming. Researchers have designed a microcontroller experiment board is cheap easy to carry easy to use. To enable the students to learn programming quickly without having to worry about the hardware. Banana Board supports the basic knowledge necessary to practice the programming of up to 22 topics. It can learn programming from basic to applied work. The connection can be done through a personal computer or connect the board to communicate

Electronic load is an importance part of power supplies testing system. For non-electronic load type it is required to replace a resister with a new one leading to complicated working procedure. The modern power electronic technology is employ to solve this problem. The electronic load can vary the value following user command. Imported electronic load is costly leading Thailand to have a balance of trade deficit. This article proposes design and implement of an economical cost 30V 1 k DC-Electronic Load controlled by Microcontroller. The tested results can confirm the validity of this proposed electronic load

This project deals with the application of microcontroller used for measuring the Q-factor of band pass filter. The procedure starts from the design creation and improvement of Q-factor and bandwidth of the filter. Solving the circuit filter frequency requirement the band must pass the filter. An instrument is necessary in the design of filtered frequency that shows the cut off at the rise edge and down edge searching the bandwidth and Q-factor of the filter. Finally the monitor will show all the values of every detail.
