Hi,
I'm an electronics noob for the most part, so please be patient with me, but here's what I'm trying to do.
I've been using an Arduino to switch a bunch of 5v Relays, only I find that no matter how simple I make my code the Arduino is unreliable and sometimes fails to trigger my relays. As I am switching the relays as two groups, one after the other, I was hoping to achieve the same effect with a 555 timer in astable mode to replicate the same effect. I was hoping it would be possible to set up one set to trigger when the 555 output goes high and the other to trigger when the 555 output goes low.
So, in trying to achieve that here's where I'm at: I have the attached circuit set up and it can switch LEDs on and off, but it's not outputting enough voltage for me to switch those LEDs for relays and have them trigger. Also attached is a picture of the 5v relay units I'm hoping to trigger.
Any idea how I can solve this? Or is there a better way I can solve this problem I just don't know about?
Thanks!
