175 Nextion display controlling and Arduino controlling a relay

In this video, I show how to control two relays. Setting two separate timers and having the relays act as single shot and constant on/off cycle with a 50% duty cycle.

Thanks, great tip on zeroing the keyboard for input.

Just want to drop you a line....great coverage of this display with Arduino....your insight, effort and descriptive processes...of course married to original and other code processes I reviewed....I have a loaded UNO with a display from streaming raw ADC values from an FSR to real time numerical distance display with a range sensor, and other various controls etc Thank you and keep up the great work.

I had the idea to do something like this to have a touch display on my microwave id like to see some examples on how you could setup buttons with pre programmed count down times on this IE. The popcorn button

Would you please put a new link to the code? The one in the bio does not work.

HI CC, is it possible to merge the content of this course with the previous video (174)?

Hey, i wanna ask something can i create array in Nextion ? Or can i Store the data from arduino in Nextion?

I try to replicate each step exactly but with my own terms like light or motor etc prints "C:CLIGHT?".0 bt0.txt="Light On". I get errors for Invalid number of arguments:prints "C:CLIGHTON?".0 & Invalid number of arguments:prints "C:CLIGHTOFF?".0 Even getting Invalid Variables bt0.txt I do not see anything different in my setup from yours. What did you skip to reveal that makes it really work? OH Ok its the 3 letter config where I messed up. The C:C is the first three letter set, then RC1 is the second set, the third set is the value. But I mean how does it recognize the difference from the second set and the value if the amount of digits in the value can be larger than three? Its basically your own string system that you like to implement. And yup no, tried the same thing "C:CLGTON?".0 & "C:CLGTOFF?" still getting Invalid number of arguments. Even with RC1. So back to my original question. What really makes this work? OMG! its a fkn comma before the 0 not a period. You cant see it well on the screen in this video. Even in the Nextion editor it looks like a damn period when you type a comma. WTF Nextion. Up at 4:53 AM for a fkn comma that looks like a dot. I would have never imagined I would be up this late losing sleep for two simultaneous unexpected problems. My cat awol doesnt come home until 3:30 am and a shitty editor that cant display a comma like it should. This better come with the price Im putting on into this effort. Now to see about the b0.txt OH I was putting bt0.text
