Toggle Flip-Flop by IC LM3900
Are you know ? IC op-amp LM3900 can use pretend Toggle Flip-Flop. One character with digital general circuit. Follow the circuit. The output Q alternate when input be pulse alternate with.

The monostable flip flop, sometimes called a ‘one shot’ is used to produce a single pulse each time it is triggered. It can be used to debounce a mechanical switch so that only one rising and one falling edge occurs for each switch closure, or to produce a delay for timing applications. In the discrete [...]

This 555 timer circuit below toggles a relay when a button is pressed. Pins 2 and 6, the threshold and trigger inputs, are held at 1/2 the supply voltage by the two 10K resistors. When the output is high, the capacitor charges through the 100K resistor, and discharges when the output is low. When [...]
