Digital Temperature Controller using arduino, here we are using arduino as main controller, this temperature controller controls the temperature of any heating device with given set points, It also displays state of the device either on or off and current temperature.
Digital code lock systems are most common on security systems. An electronic lock or digital lock is a device which has an electronic control assembly attached to it. They are provided with an access control system. This system allows the user to unlock the device with a password. The password is entered by making use of a keypad. The user can also set his password to ensure better protection. The major components include a keypad, LCD and the controller Arduino. This article describes the making of an electronic code lock using arduino. Continue reading Digital Code Lock using Arduino
7-segment displays are most popular in panel meters, It can show direct numerical value on display, It’s cost is low and display size bigger than LCD’s. Lets interface four digit display, most of the time four digits are enough to display data. Continue reading Digital Voltmeter using Arduino
LED bar-graph displays are much popular in battery level indication, water level indicator applications. Most of the inverter units have LED bar-graph display on its front panel. As we have seen in previous application we used only one LED to indicate battery level. With reference to above application we are showing voltage level on LED bar-graph display. Continue reading LED Bar-graph Display
The objective of this project is to determine the distance of underground cable fault from base station in kilometers using an Arduino board. The underground cabling system is a common practice followed in many urban areas. There are many electrical, telephone and other signal cables are laid underground.
