Hi. I've been playing around with PWM with my 555 timer and was curious how I would go about adding a "reverse"? Would I use a dpdt relay or an h-bridge or are there other methods? I'm not exactly asking for someone to just post me a schematic or anything, I'd just like to know how it's done, but if you have an example I'd love to see it ![Big Grin :D :D](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Thanks ahead of time.
