[Music] viral science the home of creativity hey friends welcome back to another video and in this video i'll show you how to make arduino timer control relay over here you can set the time with the push buttons and you can see them on the display as well you can set hours minutes and seconds and all this thing is stored in the eprom memory of the arduino so if the power cuts off the settings are stored and you can just press the set button and this thing will start working [Music] this video is sponsored by jlc pcb jlcpc is one of the lead manufacturers of pcbs at very low prices so just add your gimbal files over here and select the quantity select the color and place your order so this pcbs looks very professional neat and clean for your projects so you can order your pcbs from jlc pcb [Music] so for this project we'll need an arduino nano liquid crystal i2c display relay module buzzer 4 push buttons breadboard bulb holder and some wires now follow the circuit diagram and make your connections [Music] [Music] [Music] [Music] [Music] [Music] do [Music] [Music] do so after completing the connections connect your arduino board with your computer and open the code now this is the code of our today's project you will find some links in the code from where you can download the libraries and add to your libraries folder as we are using the eprom memory i've also declared it as well below this you will find some pin initializations and this is the complete code so you just have to select the board select the port and upload the code now we'll connect the bulb holder to our relay module i have cut one of its wire and will connect both the ends of this wire to our relay module and make sure you be very careful while doing this as we will be using a high voltage current over here [Music] here we have all the buttons set down up and mode button so while pressing the mode button you can set the seconds minutes and hours you can use up and down arrow keys to select the digits and when you press the set button the current value will be stored and it will start working [Music] [Music] [Music] [Music] so friends if you like this project then do hit that like button share this video with your friends and also don't forget to subscribe to my channel for more such videos and i will see you in the next one do subscribe and press bell icon to get instant notification for new video [Music]
