What type of data can be input into the LSTM algorithm?

I have voltage data according to time. The time range is from 0 to 460 seconds and samples were taken at irregular intervals e.g 0.2s, 1.3s, 1.7s e.t.c. The data has been labelled with two classes. I want to make a classification algorithm using LSTM which can predict the two classes in my dataset. How do I prepare and input the dataset into my LSTM algorithm?

The dataset is attached.

Thanks in advance.
