Please help me

I'm a long time grower using Hpa & Lpa systems and want to control my multiple timers with an Arduino. I'm a noob to programming but will learn it. I bought the plant watering system that came with the Leonardo board and moisture sensors etc. We hooked it up and plugged in the example code to make the led blink which was fine. We couldn't figure out how to stop it from blinking and believe we may have erased code as the oled screen now no longer shows any readout.

I'm stuck, and need quidance in some form to move Fwd. Maybe the screens broken or the board is messed up with us handling it, but we deleted something, thinking it was the blink code and no screen.

I really would like to move Fwd here. Thanks.

Can you post a link to the datasheet for the system that you bought?
