I need some help. I have been using a lot of the codes posted out there to create my Frankenstein code. The objective is to use the blynk app to control a stepper motor to open my blinds. I would like to have two modes, one for manual control and the second as an alarm. (It will be nice to wake up too!!)
Setup:
Arduino Uno
ESP8266
Adafruit Motor Shield V2
Stepper Motor
I have a working code, that connects to the blynk server, controls the stepper motors (Manual Mode). The part I am stuck at now is making the alarm work. I saw was using the post with Costas great example. But now I am at the last steps and running low on my memory on my Arduino UNO. I could use some help to:
- condense my code to run more efficiently
- get the alarm to trigger.

As you can see from my code, I have the simple timers commented out. As I am getting farther in the project, I am really strapped for memory on the Arduino UNO. As I am at the last steps of which I think for triggering the timer for the alarm, I am out of memory. I had difficulties earlier on trying to figure out how to make the push buttons update, so found an example to force the update with (below) and found success:
BLYNK_WRITE(VIRTUAL_OPEN_PIN)
{
int DOpen = param.asInt();
if (DOpen==1) {
OpenB();
Blynk.run();
// DOpen=0;
Blynk.syncVirtual(VIRTUAL_OPEN_PIN);
}
}
Please help. I’m new to this and my background is not in coding, its actually building the thing (mechanical).
But the UNO is a bit lacking on the memory side.
) And it has been running 24/7 as my testbench, uploading examples and testing them for… what… 2 months exactly today.
… Ha! OK, actually I have been a longterm Arduino user and just don’t believe their time is up, even with IOT, but as with any mashup, they do add to the setup and troubleshooting.
