CODE void setup() {   Serial.begin(9600);   pinMode (4,OUTPUT); } void loop() {  if (Serial.available()) { char c = Serial.read (); if (c == '1'){   digitalWrite(4,HIGH); } else if(c=='0'){   digitalWrite(4,LOW);   } if (digitalRead (4) == HIGH) {   Serial.println ("LED ON"); } else {   Serial.println ("LED OFF"); } }   } How to make Arduino smart Home automation system. In this project I will show you control your home Electrical bulb magnet door lock AC machine using serial monitor command. this Arduino code you can download my blogger web site.

How to Align Satellite dish tv antenna. Search your Satellite and and find Azimuth Elevation and LNB angle. then mount your satellite in safe Place root of balcony. keep your partner near the TV and you turn antenna one side very slowly, turn 2 degree to one site wait five second and ask your friend signal strength an quality if not increase turn same same direction 15 degree. if not do the same ting other detection. then 2 degree change the elevation and align the antenna. try to take good signal strength an quality. Finally rotate the LNB and try to get good signal quality . https://www.lyngsat.com/
