Merge several sketches in arduino

Hello,

I want to merge several working sketches.

The goal is to write all the logs to one file.

Could someone help me please.

Sketches are

1.-Ultrasonic to read the distance

2.-Temperature and humidity

3.- Write to sd-card

4.- Rain gauge

Regards

Louis

The Arduino is a learning platform. There is no way to merge sketches. Each program stands alone, with all lines in proper order, and should have no extraneous lines. As a programmer, you need to know what every line does and why. The only exception to this rule involves use of libraries, like that used to write SD cards.

Study each individual sketch and use only the lines you need in the final product.
