Arduino Tutorial : Controling 4 relay module for use with a 5 volt water pump

In this video I used the following supplies to control a 4 relay module with a arduino
- Arduino uno
- Bread board
- 5-volt water pump
- jumper wires
- 1-4 relay module
- Fish tank tubing

The code is below

byte pump1 = 7;
byte pump2 = 10;
void setup() {
Serial.begin(9600);
while (!Serial);
pinMode(pump1, OUTPUT); // variant low/high
digitalWrite(pump2, LOW); // variant input/output
}
void loop() {
digitalWrite(pump1, HIGH); // pump1 deactivated
//pinMode(pump2, INPUT); // pump2 deactivated
delay(2000);
digitalWrite(pump1, LOW); // pump1 activated
//pinMode(pump2, OUTPUT); // pump2 activated
delay(2000);
}
