The accurate and precise transport of the small amounts liquid by syringe pump is widely used in many fields. In this paper, an Arduino-based fabricated using computer DVD (digital versatile disc) drive. For fabrication pump, low-cost electronic components such as Arduino microcontroller, a stepper motor, motor driver, display are used. tray-loading mechanism drive (close/open tray for insertin...
Increase in the population demands healthy food, clean air, fresh water and high secured life. To fulfil above demands, spectrometers such as ultraviolet, Fourier transformation infrared, Raman, HPLC, gas chromatography are used confirmation tool for identification of materials. The cost space above-mentioned instruments more to build low-cost spectrometer with efficiency is a challenging resea...
