In this tutorial we are going to learn about Interfacing 7 segment display with an Arduino, There are two types of 7 segment displays available in the market so we will be learning how they differ when we interface them with Arduino.
Lets make a motion activated switch using PIR sensor, BC547 transistor and 5v relay.
Let’s learn how to use a touch switch with a single relay or relay channel to control the relays. So that we can drive high voltage appliances using touch switches.
Here we are going to learn about how to use LDR (Light Dependent Resistor) with Arduino and we are going to do a small project based on the LDR sensor.
