Try out different strumming patterns and rhythms. Once you're able to produce a good sounding chord, try strumming it at different tempos and rhythms. Rhythm is based on your strumming pattern, and how long you're holding your notes. Try a basic 1-2-3-4 beat, otherwise known as a 4/4. The number on the top represents how many beats there are in the measure. Try strumming up and down in different progressions to create a different sound for your rhythm. Once you get a basic rhythm down, you can start to incorporate quicker or slower strumming.
Electric tuners are easy to use and very accurate. Hold it to the guitar and pluck the high E. The tuner will tell you if the guitar is "sharp" (too high) or "flat" (too low). Pick each note and tighten the string to make it go higher, or give it some slack to lower it. Make sure the room is quiet when using a tuner because the microphone on the tuner can pick up other sounds.
