![Example Dataset 1.png](/proxy/?url=https://content.instructables.com/FSP/PMZD/LXHK46UG/FSPPMZDLXHK46UG.png&filename=Example Dataset 1.png)
Find a proper dataset for individual character recognition. Build the basis of you dataset on annotating them individually.
Expand you dataset with text or word images, where characters are all being annotated.
Testing and Improving Dataset

Train a small model to test the accuracy, and potential short comings in your dataset..
Model Trained

Bolster your dataset and retrain with a bigger model and higher epochs.
Connection Pi

Set up a raspberry pi connection with your host computer, and make a base set up with the lcd display.
Lcd Display
