I used to use this site, its pretty good it. At the start of every lesson have about 4-5 characters to learn with both sound and picture examples.m after a couple of lesson you will have a mini quiz to see how much you learned so far. https://www.nihongomaster.com/lesson/view/17/welcome-to-nihongo-master

For learning hiragana and katakana I really liked this site, she writes really beautifully. After 1 week you have to pay. Or make another e-mail account, whatever.
