Hello Engineers. At places like small gatherings or meeting halls, small conferences, and classrooms its good to employ a visitor counter. This counter will count the visitor number of persons entered in the room or hall. The circuit explained in this tutorial today, is using two CD4026 ICs with two 7-segment LED display. This Digital … Read more Visitor counter circuit using IC 4026 & 7-segment display
Hello engineers, Sometimes we need a little or less light is some parts of our home during the whole night. Areas like our lawn / our Garden area/parking lot during the whole night time. Also, we want to save electricity and energy for that, So, today I am going to discuss a Solar automatic night … Read more Solar automatic night light | Solar auto on-off night lamp
Hello engineers, In this article I am going to share an LDR operated laser light security Alarm system. This circuit having LDR as the light-sensing component. This circuit discussed here has a relay that simply changes whenever the laser falling over LDR is interrupted and then Buzzer turns ON.So let’s get started with understanding in … Read more Laser Light Security Alarm using LDR | Burglar Alarm
Hello guys, today I am going to tell you an easy way to make an Automatic night light circuit(automation) without using any micro-controllers or development board. With a circuit diagram as well as a simulation video of working of this project. This is possible with a simple analog circuitry using some active components as well … Read more Automatic Night Light circuit using LDR and Relay
