Schematic Diagram

Working principle: STC15W408S single-chip microcomputer is used as the main control, the special AD chip HX711 for weighing samples data, and the digital tube is used as a display device to display the weight; there are four side-foot touch buttons as human-computer interaction channels.

Precautions

1. The kit does not have a power supply.

2. Individual components such as resistors and capacitors are temporarily out of stock. We will replace them with components of other nearby values based on their symbolic circuit principles. The blue metal film resistors may be replaced with gray carbon film resistors and gray carbon film resistors. It is also possible to change to a blue metal film resistor, which has the same effect.
