8*8 dot matrix--51 development board

Overview

1. Internal principle of dot matrix: Column (COL) is cathode, row (ROW) is anode. For example: to light up the first light, connect row 1 to high level and column 1 to low level. The same goes for the others.
2. Image source link: https://m.renrendoc.com/paper/102198250.html, with related programs.

How to replace the 125khz low frequency antenna with a piezoelectric ultrasonic receiving circuit
The 125khz card reader originally used a 125khz 3-axis magnetic core coil. The chip can use only one coil input of the antenna. Each channel receives with a 1mv sensitivity. Now according to the proje
