Well your question wasn't specific so I'll tell you how to set it up along with using it.
To set it up, press the menu button on the left hand side of the camera. Go down to the wrench button and scroll down a ways until you see "Self-timer delay." Go to that and select however many seconds you want.
To use it, press the Fn button underneath the D3000 sign. Then, click the button you would press to normally take a picture and it should work.

Sure! You also should consider the Canon 50D.
One tends to use a Nikon remote to control a Nikon camera. This can be used when one is attempting to take a self portrait, or in conjunction with a tripod.
The K1000 is a fully manual camera, only. It will be necessary for you to buy a self timer winder. This attaches to the shutter release and is extremely easy to use. Hunt for the wind down self timer on ebay. Costs $ 5 to 8.
The older Achiever 632T Auto Thyristor flash unit can work with a Nikon D3000, but caution is advised due to the potential for high trigger voltage from the flash. Many older flashes have trigger voltages that exceed the safe limits for modern digital cameras, which can risk damaging the camera's circuitry. It's best to check the flash's trigger voltage and compare it to the D3000's specifications or use a voltage-reducing adapter if necessary. Always test with caution to avoid any damage.
To set the self-timer on a Canon 70D camera, first press the "Drive Mode" button on the top of the camera. Then, use the main dial to select the self-timer option, which is represented by a clock icon. Finally, press the shutter button to start the self-timer countdown.
The Nikon N50 uses the Nikon F-mount, which is compatible with many Nikon digital cameras. Most Nikon DSLRs, such as the D3000, D5000 series, and higher-end models like the D7500 and D850, can use these lenses. However, be aware that some features, like autofocus, may not be available with older lenses on certain digital bodies. Always check compatibility with specific lenses and camera models before purchasing.
To set up and use the self-timer feature on the Canon 70D camera, first, locate the self-timer button on the camera. Press the button and use the dial to select the desired delay time (usually 2, 10, or custom seconds). After setting the delay time, compose your shot and press the shutter button. The camera will then count down before taking the picture.
"Using software such as Nikon recovery software will allow you to recover all the data on a memory card. Very easy to use and self explanatory, go buy the Nikon software and the directions will be included."
Yes
Yes, you can. Nikon uses Nikon F-mount to connect the lens to the camera. Sometimes other manufacturers change their mount, but Nikon never did, so you can still even use analog lenses.
