In this electronics project, we aim to create an automatic plant watering system that automatically shuts off when the soil reaches the desired water level. We have already published a project on an automatic irrigation system using a PIC microcontroller. In this circuit, we utilize a basic concept: dry soil has high resistance, while wet … Read more
Automatic street light control is a good concept that aims to bring efficiency and convenience to our everyday lives. In this article, we explore a simple yet effective circuit diagram that employs transistors and light-dependent resistors (LDRs) to automate the operation of street lights. Unlike previous designs that relied on microcontrollers, this analog-based approach utilizes … Read more
The 12-volt 1.3AH battery charger circuit diagram is a highly practical design that utilizes the L200 voltage regulator and an over-voltage protection circuit. It employs an optocoupler to provide feedback, allowing precise control of the voltage across the battery by efficiently toggling the L200 voltage regulator on and off. This circuit diagram is an excellent … Read more
This article focuses on a widely-used regulator that serves as a power supply in numerous electronics projects, microcontroller-based projects, and embedded system projects. It is particularly beneficial for engineering students who may not have access to expensive power supplies but still wish to delve into the field of electronics and utilize them effectively within their … Read more
