Automatic Plant Watering/Irrigation System Using Arduino Uno This project monitors the moisture of soil and waters it by AC pump. Components required  Hardware Arduino UNO Soil Moisture Sensor  5 V 1 channel Relay Module AC-Pump-240-Volts Jumper/Connecting Wires 5 V DC Adapter Software Arduino IDE Warning: - AC is very risky and accidental shock could be fetal, so be sure to pursue appropriate safety precautions.  Predictable Designs assumes no accountability for any injury that may happen by following this tutorial. Circuit and Working The circuit is built using Arduino Uno, Soil Moisture sensor and a 1-channel relay  or as per the requirements. .  The step-wise working is as follows:       Step1:  Upload the sketch in Arduino Uno. A Sample sketch is shown below:  #define PUMP_ON 13 #define SEN_IN 2 void setup() {    pinMode(PUM...

Bike Automation using Arduino UNO and Android App Bike Automation The aim of this project is to control a bike using a mobile host (Smartphone). Components required  Hardware Arduino UNO HC – 05 Bluetooth Module  5 V Relay two channel Jumper/Connecting Wires Smart phone 7805 Voltage Regulator Software Arduino IDE Android App Circuit and Working The bike automation circuit is built using Arduino Uno, Bluetooth Module and a 4-channel relay or as per the requirements. Using a 4-channel relay we can control four equipments. The step-wise working is as follows:       Step1:  Upload the sketch in Arduino Uno. A Sample sketch is shown below:       int relay1 = 8; int relay2 = 9; int relay3 = 10; int relay4 = 11; String readString; void setup() {   Serial.begin(9600);   pinMode(relay1, OUTPUT);   pinMode(relay2, OU...

Home Automation using Arduino UNO and Android App Home automation means automatic control of electrical and electronics appliances. It includes Lighting, switching and controlling appliances. In a home automation system we have a mobile host controller and a number of client module such as home appliances. These appliances are connected through relay, Bluetooth and micro controller.  The aim of this project is to control home appliances using a mobile host. Components required  Hardware Arduino UNO HC – 05 Bluetooth Module  5 V Relay two channel Jumper/Connecting Wires Smart phone 5 V DC Adapter Software Arduino IDE Android App Warning: - AC is very risky and accidental shock could be fetal, so be sure to pursue appropriate safety precautions.  Predictable Designs assumes no accountability for any injury that may happen by following this tutorial.
