Q: What is the speed of the linear actuator?

尋ねた BG441812575 に 2021-11-27 04:41:03

MihaiP Depends on the stepper motor driver. Count on several seconds per 100 mm, as fastest move. The lowest is as slow as you want!

Q: Does the SD card on this module work on the Arduino Mega ?

尋ねた BG154735114 に 2021-10-22 11:45:17

MihaiP Surely ! You can watch pictures from SD on the display, with appropriate Arduino library.

MihaiP Not recommended. Notebook manufacturers require to use only their adapters, since most of them are not just AC-DC converters.

MihaiP No, it reads the sound files from SD only. There are other boards for what you need.

MihaiP Zero volts is wrong! Possible causes: Power it at 3.3V only! Use analog read but in a 3.3V board! My readout: about 620 (2 V in air) and 310 (1V) in water. You must calibrate yours.

MihaiP Check the switches of the board. Set it to Mega and test it in Arduino. Works fine. Then try WiFi alone. All together is for advanced users.

Q: it says adjustable. how to adjust?

尋ねた BG101554944 に 2020-12-12 06:51:01

MihaiP You can adjust with the small trimmer: any output voltage between 0 and about 1.5 V below the input voltage.
