Oscillator
Connect relays, batteries, and switches as follows
Figure (1)
Imagine what happens when the switch is closed?
Circuit conduction, magnetic magnet generated magnetic, attract metal pieces pull down, metal parts lead to circuit disconnection, circuit disconnection and lead to the loss of the magnet magnetic, so the metal piece fl back to the original, leading to the circuit again conduction... the cycle is endless
Description: After the switch is enabled, the metal parts are continuously connected and disconnected, and the Quick Disconnection causes the continuous vibration of the metal parts. This circuit is called an oscillator.

See figure 3 again)
Figure (3)
Switch A is off. Switch a' continuously switches between open and closed. Always + 5 V voltage at the V side, and the output end is output at intervals of + 5, 0, + 5, 0...
The connected light bulb will flash, light up when there is electricity, close when there is no electricity
The output sequence is similar to (22). The height indicates + 5 V, and the low value indicates 0 V.
