Table of Content RF BASED SMART HOME AUTOMATION SYSTEM © GPL3+ Step 5: Example: Light Sensor Hi , i am using the relay and Filed Under: Electronic ProjectsTagged With: Arduino, gsm, home automation GSM module’s pin Tx and Rx is directly connected with Rx and Tx pins of Arduino. And power supply adaptor is also connected with GSM module. The ground of both GSM and Arduino should be connected with each other otherwise system will not work properly. Andrelaysare connected to digital pin 10, 11, 12 of Arduino for controlling light 1, light 2, TV respectively using ULN 2003 IC. ULN2003 is a high-voltage high-current Darlington transistor arrays. 16×2 LCD’s commands pins RS and EN is directly connected with pin 7 and 6 respectively and Data pins d4, d5, d6, d7 are connected with 5, 4, 3, 2 pins of Arduino. First, we start by including the software serial library, which will be used to establish communication between the HC-05 Bluetooth module and the app. If there is any error in the...
