The temperature control and monitoring system in the freezer room has an important role maintaining quality of food raw materials. Freezer space is used to store materials keep them fresh undamaged. However, if compartment not properly monitored, may be damaged which can affect their safety. Therefore, IoT-based was created using Wemos D1 R2. design this prototype uses hardware, namely WeMos R2...

The paper presents some practical solutions that have been used to convert stationary laboratory workstations (used in the teaching of analog and digital electronics, microcontroller programming embedded systems) remote learning. presented enabled students work conditions similar standard classroom – using real circuits measuring instruments. Examples are: stepper motor control, generation a PW...

This paper analyzes the position control of a master-slave synchronization robotic arm driven by D.C. motor using PID (Proportional, Integral, and Derivative) controller with software hardware design. works to achieve exact desired simultaneously for master slave robot minimal defects. The transfer function arms used in this research is calculated black box modelling. MATLAB Simulink block test...

Biological and chemical reactions involved in physiological processes are often complex and very sophisticated. Such processes can be mimicked in the laboratory to obtain important knowledge, valuable for the development of new diagnostic methods, drugs and biosensors. This thesis includes investigations of bio-functionalized surfaces that can be used as model systems to mimic naturally existin...
