Help to design a Relay Switching circuit with timming delays

relay switching circuits

Hi.

I need some help to design and build a circuit that will switch two relays and will work as follows:

To activate Relay 1. Provide power to the circut non continuous (in three seperate intervals

withing a fixed time, say 30 seconds). Another way to explain it: provide power, tune off, provide

power, turn off, provide power and all this withing a fixed time period.

To activate Relay 2. Same as above but in this instance provide power twice withing a fixed time

say 15 sec.

All ideas welcome. Can I use the 555 is some sort of combination?

Thanks in advance.

In Australia you can easily get hands on PICAXE-08 (looks the same as 555 – 8-pin DIP) ..
Altronics sells it for A$4.50 or you can get PICAXE-08 kit for A$35 ..
Programming software is free, all what you need is a serial port in your PC ..

555 is just a timer, whereas PICAXE can be programmed to react to certain situations the way you like and your circuit shouldn’t be difficult to make with this small micro ..
