Hi guys My project is simple ( but not for me) I have an Arduino uno ,one FLUIDS / LIQUIDS FLOW SENSOR 5-15VDC 15mA and a relay board with 4 relays. only using two of the relays. The reason for my question is as follows it keeps counting up. l/h. I want the board to switch the relay 1 on when it…

no i want them to work like you original sketch. just the relays must turn off after been on

[image] StefanL38: The wires of the switch shown in the picture are connected to ____________nothing at all If the switch is opened then __________nothing at all If the switch is closed then __________nothing at all The mechanic lever of the switch is pushed when __________nothing at all t…

const byte PinRly2 = 12; bool flow; bool flowLst; unsigned cnt; unsigned cntLst; float flowRate; const float RateLo = 1.0; const float RateHi = 10.0; unsigned long PeriodMsec = 500; char s [80]; // ----------------------------------------------------------------------------- void loop (…

And now you expect that this code will be modified to switch off the relays after 10 seconds. And 5 posts later you will come up with a new detail that it is still not working as you want it which results in another 10 posts of asking back until your description is clear enough what must be change…

[image] StefanL38: After how much time shall the relays turn off? The relays should switch off after 8-10 sec using the above sketch. and repeat it self in that order!
