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 […]
Lithium-ion vs. Lead-Acid batteries – Detailed Comparison
Hello Engineers, In today’s article, I am going to explain in a bit brief about Lithium-ion vs. Lead-Acid batteries and also their merits &demerits. How are they different? How is the one better than another. Their chemical and electrical properties. Also Lithium-Ion vs. Lead-acid batteries. so let’s get started. Lithium-ion vs. lead-acid Tabular difference at […]
L293D Motor Driver IC and interfacing with microcontroller
Hello Engineers, Whenever making motor-based projects using any microcontroller IC we need more power in order to operate the motor. This power, can not be provided by any of the microcontroller ICs as motor requires a lot of power than the microcontroller consumes. For this, we need to use a motor driver with a microcontroller(L293D […]
UPS Power grid for wifi router and broadband 12v 1.5A.
Hello Engineers, A non-stop internet connection is a necessity for all. Although in developed cities, a power cut is very uncommon. But still, it takes place and if your wifi and landline connection isn’t connected to the inverter, then your internet connection and landline may not get power and it is interrupted and all the […]
IC555 delay timer for controlling the on-off time of AC devices
Hello engineers, In this article, I will explain how to control AC appliances ON-OFF time using the IC555 Delay timer circuit that I have already discussed in the previous article. The delay timer ON-OFF circuit is similar and has just a few more components. So, Let’s Starts with the materials required and diagram followed by […]
