I am heading to Edinburgh in March of next year abd I was wondering what is the best day tour you can do. I am hoping to see a lot in one day of William Wallace.
There's not much to see
Elderslie was where he was born, Dumbarton Castle was where he was captured, Wallace Monument is where he was remembered. It's not much of a tour, really. And the Stirling Bridge of the battle is long gone.
There may be a tour out there but it's going to be mostly driving
I've not been able to find any tour operators running a day trip from Edinburgh specifically geared to William Wallace. There are a couple of private tours - but that is going to work out expensive...

What bits of Wallace's history do you want to see? As others have said Wallace and of course King Robert (the real Braveheart) were circa 700 years ago and we've had the decorators in a few times since.
I was wondering about museums to see of both William Wallace and Robert the Bruce and also notable landmarks or what not.
You could visit Dunfermline Abbey, which is a short distance outside Edinburgh, and see the spot where Robert the Bruce's remains lie (well, most of them). The Abbey and area is beautiful and well worth a visit. There are also some memorials in or near Stirling - and of course, Robert the Bruce was at the site of Stirling Castle when he had the original destroyed.
Here are some places put together by VisitScotland.

ETA: Rabbies, which is a very good tour company, also does some tours that contain bits about Robert the Bruce. You can find more information here: https://www.rabbies.com/en/blog/robert-bruce
The Stirling area is key to both King Robert and to William Wallace. The Wallace monument is north of the city, the NTS Bannockburn site to the south west. Bannockburn is one of the most important events in Scottish history and the museum has a lot about King Robert.
You are going to need however a lot of imagination about what places looked like, Stirling Castle is now largely a Renaissance palace now, though the statue of King Robert outside is a reminder of the importance the castle had.
