Make sure the LEDs are connected correctly (positive side to a digital pin and negative side to GND). It could also be a broken jumper wire, try to change the jumper wires.
This code will work on that board but to add the extra functionality to upload data, you'll have to try the Arduino Cloud IoT, they have tutorials on how to upload sensor data.
Can you tell which online simulator you have used to show connection?
I'm using an offline software called Fritzing.
hi this is great but the led lights wont light up when i scan the card

Do you have code that will work with UNO R4 Wifi board?
