LCD INTERFACING Module

Overview

LCD stands for Liquid Crystal Display. LCD is finding wide spread use replacing LEDs (seven segment LEDs or other multi segment LEDs) because of the the ability to display numbers, characters and graphics. This is in contrast to LEDs, which are limited to numbers and a few characters.

LCD INTERFACING MODULE:

Features :

• Can display 224 different symbols.
•  Low power consumption. 
• Powerful command set and user-produced characters
• 5 x 7 dot matrix format.

Digital Dimmer Module

Overview 

The board can be used in applications where dimming of 110-220V AC power is required like dimming of bulb or fan. The input can be simple 4 bit high/low signal from microcontroller working at 3V or 5V which is isolated with the use of opto-couplers. Total of 16 levels of power control can be set from totally off(0%) to full on(100%) as per input control levels.

Digital Dimmer Module:

 Features:

• Works on AC power supply
• Load Capacity 12 Amp AC
• Isolated Input 3-5V DC
• Works from any microcontroller input
• 16 Levels of Control
