Keywords

💡Arduino

Arduino is an open-source electronics platform that is used to build various interactive electronic projects. In the context of the video, it serves as the central processing unit for the timer control relay system. The script mentions using an 'Arduino Nano', which is a specific model known for its compact size and versatility, suitable for projects like the one described.

💡Timer Control

Timer Control refers to the ability to set and manage time intervals using a device or system. In the video, the Arduino is used to create a timer that can control a relay, which in turn manages the operation of an electrical device based on the set time. The script explains how viewers can set hours, minutes, and seconds using push buttons.

💡Relay

A relay is an electrical switch that is operated by an electromagnet. In the script, a 'relay module' is used to control a high voltage current, such as that which would power a bulb. The Arduino sends signals to the relay to switch the current on or off based on the timer settings.

💡Push Buttons

Push Buttons are simple input devices that, when pressed, send a signal to a system. In the video, '4 push buttons' are used for setting the timer, including up and down arrows for adjusting the digits. The 'set button' is specifically mentioned for storing the current value and initiating the timer.

💡Display

The term 'display' in the video refers to a device that shows information, such as the time set on the timer. The script mentions a 'liquid crystal I2C display', which is a type of screen that uses liquid crystals to display characters and numbers, allowing users to see the time they have set.

💡EEPROM Memory

EEPROM, which stands for Electrically Erasable Programmable Read-Only Memory, is a type of non-volatile memory used to store data even when the power is off. The video script mentions that the timer settings are stored in the 'EEPROM memory of the Arduino', ensuring that the settings are retained even if there is a power cut.

💡JLCPCB

JLCPCB is a company mentioned in the video as a sponsor. It specializes in manufacturing Printed Circuit Boards (PCBs) at low prices. The script encourages viewers to order their PCBs from JLCPCB for professional, neat, and clean project components.

💡Buzzer

A buzzer is an audible signal device that makes a sound, often used for alerts or notifications. Although not explicitly detailed in the script, a 'buzzer' is listed among the components needed for the project, suggesting it may be used to signal the end of a timer interval or provide other auditory feedback.

💡Breadboard

A breadboard is a device used for building and testing electronic circuits without soldering. The script instructs viewers to 'follow the circuit diagram and make your connections' on a breadboard, which is essential for prototyping the timer control relay system.

💡Bulb Holder

A bulb holder, as mentioned in the script, is a device that holds a light bulb in place and connects it to an electrical circuit. The video describes cutting a wire from a bulb holder and connecting both ends to the relay module, demonstrating how the timer can control the operation of a light bulb.

💡Code

The 'code' in the video refers to the programming script written for the Arduino to control the timer and relay functions. The script mentions uploading 'the code' to the Arduino board after making the necessary connections, which is a crucial step in bringing the project to life.
