Good day to all.
Hope your all well.
This project is difficult for me.
What I have:
Arduino UNO R3
TM1637 Display (CLK,DIO)
Micro Switch with a 10k Resistor inline with 5v
2 Relay module
Matrick 4x3 key pad with 7 connections
This is a down counter as the micro switch is press each time.
The key pad is the value input on the display.
The micro switch will down count the deeply value.
On the key pad the * button must activate both relays.
If display counter is at zero the relays must de-activate.
If press again the system must reset to zero.
On the key pad the # button must activate only one relay.
If press again the system must reset to zero.
The relays must only work as the *,# buttons where press and then the count starts counting down.
This unit will control a water pump (relay 1) and a solenoid valve (relay 2)
Thanks for helping me.
as this is still new to me.
Have a nice day from
Rick South Africa.
