Pushbutton*1 Resistor 220R*2 Relay *1 130 Motor*1 Fan*1 Wiring Connect the button with a 220Ω pull-down resistor in order to hold the logic signal near zero volts when the button is disconnected. The relay has 6 pins. Pin 1 and 2 on the relay are input signals and are separately...
Two normally open push button switches are connected to DP2 and DP3 to ground. Internal pull ups are used - switch closed reads as false or 0. Instead of constantly typing digitalRead(PIN) I created subroutines S1() and S2(). If either S1() or S2() are called a closed switch returns...

We will use a simple OR logic control function to process the pushbutton switch control signal, turning on the DC motor when either of the two switches is pressed. The switches will provide a 12 V control signal, which is provided by an external supply, to the Opta’s input terminal ...
