A super-fast and super-bright flashing LED light, perfect for growing plants (and you can record the temperature too)!

Jun 22, 2020 · Simple Temperature, Humidity data logger with Time-Stamp and control LED over internet.

Dec 4, 2017 · Give this the parameters you want and the LEDs will light up according to the temperature cold blue, green fine, red hot

Explore comprehensive documentation for the Arduino UNO Temperature Monitoring System with LED Indicator project, including components, wiring, and code. This project uses an Arduino UNO to monitor temperature via an LM35 sensor and indicates status with a red LED.

This design is made to keep track of the temperature in a room. You give it the parameters you want and it will light a blue LED if it is too cold, a red LED if it's too hot, and a green one if it's just right.

In this tutorial I make a temperature and light sensor data logger with an Arduino so that I can test different locations for plants or places to sleep outside in the summer that don't get to much sun

Mar 20, 2025 · MAX7219 4-Digit LED Matrix Display Clock & Temperature Monitor with Arduino. In this project, we will design and build a fully functional digital clock and temperature display system using an Arduino UNO, a MAX7219 4-Digit LED Matrix Display, a DS1307 Real-Time Clock (RTC) Module, and a DHT11 Temperature and Humidity Sensor.. This project will allow us to display the current time, date, day of ...

This project utilizes an Arduino UNO to monitor temperature readings from an LM35 temperature sensor and indicate the temperature range with a red LED. The LED is connected through a 4.7k Ohm resistor and is controlled by the Arduino's digital pin D13, while the temperature sensor's output is read by analog pin A5.

Adafruit LCD Shield Kit w/ 16x2 Character Display - Only 2 pins used! This kit uses only 2 arduino pins (SCL and SDA) saving I/O pins for other purposes. I used to work with old mechanic devices that registered the temperature and humidity in computer rooms.

Introducing the Temperature-Sensitive LED Indicator, a smart and interactive way to monitor ambient temperature through vivid color changes. This compact, Arduino-powered device uses an RGB LED to instantly communicate temperature shifts, making it a perfect tool for DIY enthusiasts, students, or anyone interested in environmental sensing.
