Description of the operation of the electrical circuit
The device consists of a direct-current pulse generator, collected on the U1 microcircuit, associated with the U2 register, and 20 light-emitting diodes, placed around the heart. Collecting generator on logical elements U1.1, U1.2, U1.3 and an hour trigger, which sets C1-R1. From the output of the pulse generator, it goes to the input of microcircuit U2, which is the last active register. With the skin impulse that comes, a high logical level will be consistently established at the outputs of the register Q0-Q7, starting from Q0, and collapsing to QS. LEDs D5, D2-D6, D3-D7, D4-D8, D17-D13-D9-D20, D18-D10-D14-D21, D11-D15, D12-D16-D19 will be sequentially lit in this manner. If the high level signal is within reach of QS, the inverter U1.4 inverts the signal, it is applied to the outputs D of the U2 microcircuits, and now, with a skin pulse, low level signals will be sequentially installed at the outputs of the U2 microcircuits And the LEDs will go out in the same sequence.

WARNING:
When folded, it is necessary to pay attention to the polarity of capacitors, LEDs and the pinout of transistors. A correctly chosen scheme does not fail and begins to work immediately
