### Motor rotation confusing.

my coding was regarding about a rain sensor to active the rotation of motor with 2 limit switch connecting to same digital inout , but i facing the problem which 2 condition can interact both condition (if.....else). the motor start confuse , keep reverse and forward. plz someone help me solve this problem for me . i need end the first condition statement before proceed to next statement. Even thou i used while(1), it's didn't working.

CODE: SELECT_ALL_CODE
`int rainsensor=1;int rainvalue=0;int rain_sensitivity=800;int buttonPin0 = 0;int E1 = 6;  int M1 = 7;                        void setup(){pinMode(buttonPin0,INPUT);pinMode(M1, OUTPUT);}void loop(){buttonPin0 = digitalRead(2);rainvalue = analogRead(rainsensor);if (rainvalue < rain_sensitivity && buttonPin0 == HIGH) {      digitalWrite(M1,HIGH );           analogWrite(E1, 225);       delay(100); }  else if (rainvalue < rain_sensitivity && buttonPin0 == LOW) {    analogWrite(E1, 0);       delay(100);                                         }// I want end the process above, to avoid interact next statement at below.if (rainvalue > rain_sensitivity && buttonPin0 ==HIGH) {    digitalWrite(M1,LOW );           analogWrite(E1, 225);       delay(100); }  else if (rainvalue > rain_sensitivity && buttonPin0 == LOW) {    analogWrite(E1, 0);       delay(100); }      }`

Hi alung92,
- your rainsensor pin is not analog. You need to set it as analog pin (e.g. A0).
- set E1 pin as output too.
- you can try using while statement to run one by one condition.

Agreed with Idris, try part by part, narrow down the possible error. When you combine everything, it is difficult to troubleshoot.
Make sure 1 part is working correct, add a little small part and make sure the additional part is working on top of the previous part. When the output is not working as expected, troubleshoot the additional part.
