Continuous sharpening of pencils can cause pencils to run out quickly due to uncontrolled time to sharpen. This research aims to design automatic pencil sharpener hardware and software based on the length of time needed to knit pencils according to pencil diameters based on ATmega 328 microcontrollers. The timing is based on the brand of pencil with the same thickness level of 2B and based on f…
The Utilization of melamine as an ingredient in making cutlery carries the risk of danger if it is contaminated with food consumed by humans. Therefore, this study aims to make a device that can detect exposure to melamine concentrations in melamine-based cutlery. How the device work is to detect exposure to melamine concentrations using melamine Molecularly Imprinted Polymer (MIP) that behaves…
