Hi All

I'm starting a little projet with a PIC chip, since I discovered that PIC Basic can make it easy for me

I have some programming skills, but I'm very poor at selecting components, so may someone more aware of the electronical side help me?

I'm want to use a 16F84A or 16F628A (i have both actually), and If possible i want to drive some low power relays directly from the chip!?

Panasonic and Omron makes 5V, 20mAh, 250ohm relays that are close to the output power of the PIC pins, but anyone ever made it work?

I'd like a single coil latching relay, maybe the TN2-K-5V of Panason..

Next thing is how to drive it safely, knowing that I should add zener diodes somewhere to dampen the coil release.
Being a single coil latching relay, I will need two pins and so, current will flow both direction.
I would prefer a relay that changes state everytime it get a pulse, so driven by only 1 pin, but I haven't seen that anywhere.


k, enought on the relays, it's already scary long
