PROJECT ON HOME AUTOMATION Requirement: - Arduino kit, jumble wires, 5v dc power supply, relay switches, ac power supply, Bluetooth module Software used:- Arduino program based on C language, java Introduction:- Home automation involves introducing a degree of computerized or automatic control to certain electrical and electronics system in a building. These lighting, temperature control, etc.., this paper demonstrate a simple home automation system which contains a remote mobile host controller and several client module (home appliances). The client modules communicate with host controllers through a wireless device such as a Bluetooth enabled mobile phone, in this case, an android based smart phone. Circuit diagram:- Program:- #define led 13 //The default baud rate of HC-05 module is 9600. The void setup code: char command; String string; void setup() { Serial.begin(9600); pinMode(led, OUTPUT); } void loop()...
