1. A driving system for driving a piezoelectric pump device, comprising:
at least one mechanical device; and
a driving circuit system electrically connected to the at least one mechanical device, wherein the driving circuit system comprises a pump-driving unit, a linear voltage-stabilizing unit, a microcontroller unit, a current-sensing unit, and a connection unit;
wherein the pump-driving unit receives a first signal, a second signal, and a third signal that are transmitted by the microcontroller unit, and drives the at least one mechanical device to operate;
wherein the current-sensing unit receives a fourth signal transmitted by the pump-driving unit so as to obtain an actuation current value of the at least one mechanical device;
wherein the linear voltage-stabilizing unit is a voltage-stabilizing element, wherein the linear voltage-stabilizing unit, the current-sensing unit, and the microcontroller unit are coupled to each other through a fifth signal and a sixth signal;
wherein the microcontroller unit executes a program to generate the first signal, the second signal, and the third signal; and
wherein the connection unit provides a reset signal, a seventh signal, an eighth signal, a 5V power supply, and a ground terminal, wherein the connection unit and the microcontroller unit are coupled to each other through the reset signal, the seventh signal, and the eighth signal.
