Hi,
I'm looking for a circuit to make a simple cyclic timer.
With "simple" I mean that every on/off cycle should be equal. Example: 2 mins "on" and 2 mins "off", continuously; would be also nice to insert a trimmer resistor to set, as I wish, the time of both cycles.
Obviously this timer must activate a relay.
The power supply will be 12 or 15 volt (this is due to the fact that I have various power adapters, which I can use for various needs).
I would prefer to keep it simple also in regards of the used components: here I have some NE555: can someone suggest me some schematics to achieve this kind of timer?
I also have one CD4060 IC: from what I can understand, should be be better to make a timer. Am I right?
Thank you.
