Thanks

Thanks

The oscilloscope is mistakenly set to measure AC instead of DC voltage

Thanks a lot :)

You need to use ESP32 inbstead ArduinoUno board

Thanks a lot :)

Yes, correct

Updated code and schematic

Thanks a lot, for the next period I am preparing another game on the same hardware

Yes, it will work

It is exactly the same device, the only difference is that in addition to rectangular pulses, the coil can be excited with sinusoidal signals (it is Audio Frequency-to-Pulse Conversion Circuit) which in practice means a magnetic field with fewer spikes which is negative feature because in this case these devices use exactly these spikes to obtain a stronger magnetic field. Another difference is the "PRICE" of this "PROFESSIONAL" device. But if you connect my device to a personal computer as described above, you can also generate such Audio Frequency-to-Pulse signals as well as hundreds of other signal formats using "Frex" software.
