Abstract
During the COVID-19 pandemic, when the educational process was organised remotely, a need arose for inexpensive laboratory equipment that could be given to each student at home. This article describes the development of an affordable and compact laboratory complex allowing laboratory work that is typically performed in an educational institution to be carried out remotely. The proposed device is based on the PIC24FJ128GC006 microcontroller. The purpose of this article is to describe the development of a two-channel USB oscilloscope with the ability to receive an analogue signal having a frequency of up to 500 kHz; a signal generator is also required. The user interface is developed in MATLAB, and a new method for multi-channel signal capture using a single-channel ADC is proposed. Notably, the cost of the device is EUR 24.
