Colin Kazim-Richards' goal was enough to see off the Gunners, but Michael Appleton will be wary of Steve Bruce's Tigers, who have won three of their last four games.
The Lancashire outfit are still chasing a play-off spot, as they currently sit six points behind sixth-placed Middlesbrough with a game in hand, and goalkeeper Jake Kean, a hero of Saturday, wants to channel the spirit shown in north London in east Yorkshire.

He told the club's official website: "There's a confidence flowing throughout the team at the minute, especially within the back four. We are a strong unit, we work well together.
"They've been outstanding since I've come into the team. It is a massive result for us, we are on a good run as it is so staying in the cup will help us.
"We can build on the defensive performance that we showed and take it on from there to the game against Hull on Tuesday. Hopefully we can build on those performances and build as a collective and go on from there."
The Tigers eased past Charlton on Saturday thanks to Gedo's second goal for the club and the Egyptian's scoring exploits have come as no surprise to compatriot Ahmed Elmohamady, who is looking to turn his loan deal at the KC Stadium to a permanent one in the summer.
Elmohamady told BBC Radio Humberside: "It's normal - he's like this all the time, he scores important goals. I've been with him three years in the national team and I know him.
"Gedo is quick, he's strong, his headers are good, he just needs to train a lot of times with the lads to keep going.
"I really enjoy being here, because we play very good football all season, and I really hope we can keep it going and get promotion.
"It will make everybody happy to go back to the Premier League. I have a contract with Sunderland at the moment so we'll see what happens."
Barnsley host Wolves in a battle between 22nd and 21st in the table. The Tykes progressed to the FA Cup sixth round with a 3-1 win over MK Dons at the weekend and boss David Flitcroft has admitted he has been inspired by the exploits of Yorkshire neighbours Bradford City in the Capital One Cup this term.
"Bradford's cup run has been very inspirational to my group," Flitcroft told reporters. "I have been inspired by Bradford and I am trying to make new heroes at this club.
"We're in the last eight of a competition I absolutely love. This competition is about families to me and I'm trying to build a family here we can be proud about.
|PLAYERS TO WATCH
|The prolific Egypt international has started life on Humberside in fine form, netting twice in three games. A lack of a regular goalscorer has kept Steve Bruce's side from kicking on and sealing a top-two spot this term - Gedo could be the man to fire the Tigers up.|
|After only managing two goals in his first 19 appearances this season, the former Rochdale man has struck six times in his last seven games and his improving form could be crucial as the Reds look to maintain their current form and scramble to safety.|
|Likely to be playing under his dad when Wednesday's clash with Leeds comes around. The winger's form has dropped off recently after a January move to Liverpool failed to materialise and a little paternal encouragement could be just the tonic.|
"We spent a lot of time and dedication preparing for the MK Dons tie. We locked the players in a hotel for two days and took them to Doncaster on Tuesday to watch MK Dons play."
Dean Saunders' side drew 0-0 with Derby on Saturday, with the Welshman being equally satisfied with his side's defending as he was frustrated with their incisiveness in attack.
"It was a solid performance and we just needed to put away the chances that came our way," he told reporters.
"We created a fair few chances and also had some balls headed back into the box where we just didn’t sniff out the opportunity. It maybe just needed someone to anticipate and poke the ball in the net with that killer touch in front of goal.
"We just didn’t have it today and on the balance of play we should have taken at least one of those chances but we did all the basics properly and on another day we might be talking about a win."
The only game to be played on Wednesday night will not be short of headlines with Paul Ince likely to be taking charge of Blackpool for the first time when they travel to Leeds.
The Seasiders have been without a permanent manager for over a month since Michael Appleton's 65-day reign was cut short by his move to Blackburn, but the former England midfielder is set to be appointed, according to caretaker boss Steve Thompson.
After Blackpool's 1-0 defeat to Ipswich on Saturday, Thompson told reporters: "There's going to be an announcement on Monday. It's going to be Paul Ince. The deal is very close to being done."
Tangerines midfielder Chris Basham is keen to move on from the weekend defeat and get back to winning ways against the Whites.
He told the club's official website: "Wednesday brings a massive game against Leeds, we all know what they are like on their patch so it's one I'm looking forward to.
"I've never played there before so it's a feeling of excitement and if we carry on with what we are doing we will get that win we deserve."
Leeds were hammered 4-0 by Manchester City in the FA Cup on Sunday and Neil Warnock has admitted he is not expecting to stay at Elland Road next season with fans turning on him as a top-sox spot looks increasingly unlikely.
"If we do not go up this season then I think everybody knows I am not going to be here," he told reporters.
"I am afraid I am going to have to get used to the chanting. I do not think I deserve that.
"The fans are so desperate to get back in the big time and when they see the opportunity fading the manager has got to be the scapegoat, the focal point.
"My contract ends this season and there is no way I want to stay in the Championship again next year."
The weekend in headlines
- Nikola Zigic will have to earn his place in Birmingham's side back after putting in "possibly the worst training session" that boss Lee Clark claimed to have seen last week.
- Blackburn have signed former winger David Bentley on loan until the end of the season. The Tottenham man made his second Rovers debut against his first club, Arsenal, at the weekend.
- Sheffield Wednesday boss Dave Jones has been handed a one-game suspended touchline ban after an altercation with Brighton coach Charlie Oatway last month.
- As Wolves look to beat the drop, manager Dean Saunders is reportedly lining up a loan move for Liverpool teenager Jack Robinson, who plays at left-back.
