I have written simple code. I want the 4 relay to turn on/off independently when switch is pressed first time Relay is active low and switch is connected with pull up resistor, initially all relays are active, relay should goes off / on after pressing button How to get rid of this blocking dela…

I don't understand what to do next ? const int Switch_Pin1 = 4; const int Switch_Pin2 = 5; const int Switch_Pin3 = 6; const int Switch_Pin4 = 7; const int Relay_Pin1 = 8; const int Relay_Pin2 = 9; const int Relay_Pin3 = 10; const int Relay_Pin4 = 12; // co…

[image] 12king: I don't understand what to do next ? Let's clear up a couple of things first: Why do you have Relay_Pin3 and Relay_Pin4 defined as inputs? How are your switches wired? Do you have external pullup resistors?

You will need 4 (four) different BWD type timers. Set a Flag when the switch goes from not pushed to pushed, turn OFF the output and reset that TIMER When a Flag is set, check to see if that TIMER has expired; if it has, reset that Flag and turn ON the output. Confirm your switches are wired as S…

[image] 12king: I want the 4 relay to turn on/off independently when switch is pressed first time here is an example of 3 independent groups of input pin / output pin and separate timers: struct Groups { const byte buttonPin; const byte outputPin; uint32_t previousMillis; }; Groups gr…

[image] 12king: I have 40000 ms the time interval. The flag is set when the button is pressed. How to configure the timer in code? When a Flag is set, how to check if that TIMER has expired; ? The code @noiasca posted will work with very little modification.

[image] ToddL1962: The code @noiasca posted will work with very little modification. Before writing the code I want to understand few things. I've been told I'll need four timers. I don't understand in the code which timer is using in code, how its configured and how can we compare the time

[image] 12king: I've been told I'll need four timers. I don't understand in the code which timer is using in code, how its configured and how can we compare the time This is the code that compares the time: if (millis() - i.previousMillis > 3 * 1000UL && digitalRead(i.outputPin) == HIGH) { …
