OUT-AND-RETURN OPERATION

Published:2013/6/21 3:01:00 Author:muriel | Keyword: OUT-AND-RETURN OPERATION | From:SeekIC

In this circuit the train only moves when S1 is pushed. After a set waiting time the train returns to its start position and then waits. The 555 timer in this circuit is configured as a monostable oscillator. The SPDT switch allows the circuit to be changed from normal operation to out-and-back operation. Two 555 timers are indicated but a 556 timer can also be used.
