Noob to Arduino: Ramps + a4998 + Stepper Test

Apologies if this seems repeated- I know other threads have asked about similar things, but are from atleast 3-5 years ago, and seem more advanced issues than my very basic one. I am a complete noob to Arduino, Ramps, Steppers, electronics itself - am a software guy trying out something to teach kids as a volunteer at summer camp.

I plan to test using the basic Stepper test posted by Robin and others, waiting for basic electronics kit to arrive.

In the meanwhile, I tried to run the Ramps stepper test in the RepRap wiki. I have added 3 a4988 drivers, attached a 5v power, like in this picture (the digital voltage indicator is reading 5.08v, even though it doesn't show clearly in the pic), the Arduino clone works with blink test, but when I attach the stepper to any of the 3 drivers, nothing happens. Checking with multimeter, no power seems to be coming to the pins the steppers connect to ( I checked with extreme end pins of the 4). Power is coming at the D10, D9, D8 outs of the Ramps board.

What might be wrong? TIA!

Have you seen this?

"RAMPS" is

Welcome to the forum.

If you mention something, can you tell what it is ?
I don't know the basic Stepper test by Robin and I would like to know which electronics kit you ordered.

There is a simulator that can simulate the project in a browser. I started with the RepRap stepper test, but I would have to change the code, because the code uses numbers for analog pins.
Here is the not-finished Wokwi project: https://wokwi.com/projects/406548648724801537

If you are looking for examples, then the Wokwi simulator has working examples. Scroll down on this page and try them all! https://docs.wokwi.com/parts/wokwi-stepper-motor

The AccelStepper is the most used library (for small and easy projects): http://www.airspayce.com/mikem/arduino/AccelStepper/index.html

Thanks everyone for your replies! I was able to get it to work, when I realized the input power was 12v 5A not 5V.

Here's a RAMPS-like Wokwi wiring with basic GCODE:
