Microcontroller based self contained material loader

Hamilton Plastics Systems Ltd. (HPSL) currently uses a control board for the operation of their hopper loaders, which have discreet digital components designed fifty years ago. The discreet digital components include timer Integrated Circuits (ICs), counter ICs and other logic gate supporting ICs. The life span of these components has decreased over time; at present, it is less than six months. The Humber team will develop a solution using a microcontroller that can be reprogrammed based on the specific requirements that may vary over time, with a Liquid Crystal Display (LCD), and electric current driving circuits with a modular power supply unit. The reprogramming capability of the proposed project has an advantage over the previous board as this one will not change the hardware for reprogramming as well as maintain a low manufacturing cost, specifically required by the HPSL.
