Building a touch control counter
The touch control counter is a fascinating project where a seven-segment LED display feature will be built and demonstrated to the reader. There are four components required to make the touch control counter operational. The four touch control counter components are the M5Stack Core2, the Freenove Projects kit Arduino Uno compatible, a transistor relay driver circuit, and a four-digit seven-segment LED display. Figure 6.24 shows a touch control counter block diagram:

The M5Stack Core2 provides a UI for operating the Freenove Projects kit onboard transistor relay driver circuit. The electromechanical relay single pole single throw normally open (SPST NO) contact provides a ground or low-control signal to the Freenove Projects kit Arduino Uno compatible. The Arduino Uno compatible will provide the latch, data, and clock signals to operate the four-digit seven-segment LED display...
