Currently the LED lamp is popular due to it’s efficiency and many believe it is a ‘new’ technology. The LED is a light source which uses semiconductors and electroluminescence to create light. In this project, LCD will be used for give your information about ADC Value from LDR. As research continues, these limitations are slowly becoming less significant. There are several tradeoffs as well, such as limited view angle, brightness, and contrast, not to mention high manufacturing cost. They are easier to read and more pleasant to work with for long periods of time than most ordinary video monitors. Of course, LCDs are flat, and they use only a fraction of the power required by CRTs. Liquid Crystal Displays (LCDs) offer several advantages over traditional cathode-ray tube displays that make them ideal for several applications. It contains everything needed to support the microcontroller simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.” For more information, you can click Here. The Arduino Uno is a microcontroller board based on the ATmega328 .It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. In this project, Arduino Uno will controlling it with ADC pin and Digital Output pin. They can be used to respond to events such as the transition from daytime to night-time (and vice versa) for home automation and gardening applications, and are often used to control street lighting. Due to the imprecise nature of photoresistors, they are unsuitable for measuring exact levels of light but are capable of detecting changes. In dark environments the resistance is high in light environments the resistance is lower. Light Dependent Resistors (LDRs) also known as Photoresistors, or photocells, are low-cost variable resistors where the resistance changes depending on the amount of light hitting its surface. It’s so simple and easy, you just need this components below If you want to realize it, it is much better. You must remember that this is just a simulation project. I will create this automatic lighting project with Arduino and Proteus 8. This is about microcontroller with LDR sensor and LED. Hello guys, i want to sharing about my simulation project.
