In this tutorial we will show you how to make a Countdown Timer using Arduino. The time duration is provided by the user with the help of Keypad and 16x2 LCD. And when the timer reaches to Zero, alert sound will be produced with the help of Buzzer.
Then, when you type 'v' to view your timer, you will see the Arduino say 1 minute and 40 seconds. Combos: Say you are too lazy with talking with your Arduino friend and you just want to get the timer started. Well, now you can cut Arduino off. Say you just want to cook ...
Timer to turn an electrical light on and off using a 120v control relay. This project will use the Programmable Clock to control the 120v control relay. Test BME280 weather device: Temperature, Humidity and Pressure. Weather module: Temperature, Humidity and Pressure. Requires: Nano with USB mi...

The updated software now includes a 4 minute timer. Step 23: Legal Issues I sometimes get question asking if this can be used to grow "California Green". Sure, it can be used to grow virtually any kind of plant. But this device is no fool-proof way of doing that as each plant, be...
Your ThingSpeak Dashboard should be receiving new random readings every 10 seconds. For a final application, you might need to increase the timer or check the API call limits per hour/minute to avoid getting blocked/banned. 2. ESP32 HTTP POST (IFTTT.com) ...
