With the help of this Countdown timer, you can control different types of electrical loads like for example Light Bulbs, Heaters, Water Pumps, Washing Machines, Fans, etc. in fact, this countdown timer can be used anywhere where you need to control anything on the time basis. As you can see, for the demonstration purposes, I have connected a 220Vac light bulb, which of course can be replaced with different types of other electrical loads. This countdown timer is very user-friendly. Let’s say I want to turn ON this Bulb for 10 seconds…Enter minutes as 0 and press the Asterisk key on the keypad… now, enter seconds and again press the asterisk key… as you can see the light Bulb has been turned ON. Now, this Bulb will remain ON for 10 seconds…As you can see the light just turned OFF… Now let’s say I want to Turn ON this light for 1 minute and 25 seconds, simply enter the minutes and seconds, and that’s it… ******************** Amazon Purchase links: ***************** Arduino Nano USB-C Type ( recommended): https://amzn.to/4ahGLdk ESP32 WiFi + Bluetooth Module for iOT Projects (recommended), more IO pins, improved speed, and supports a Lipo Battery: https://amzn.to/3v40DkE LCD 16x2 i2c: https://amzn.to/2P5XOuF 4x3 Keypad Arduino: https://amzn.to/3rt24kP One-Channel Relay Module: https://amzn.to/3sr2UQm Other Must-Have Tools and Components: Top Arduino Sensors: https://amzn.to/3vZbnfM Super Starter kit for Beginners https://amzn.to/3cq56C5 Top Oscilloscopes https://amzn.to/3ctF3d8 Variable Supply: https://amzn.to/2PEAqE7 Digital Multimeter: https://amzn.to/2QGRPg1 Top Soldering iron kits: "best" https://amzn.to/39nqDtb Top Portable drill machines: https://amzn.to/3suQMh7 Jumper Wires: https://amzn.to/2NYPEDA 3D printers: https://amzn.to/3ruG1dt CNC Machines: https://amzn.to/3cuZWVv Electronics Accessories: https://amzn.to/3sueV7z Hardware Tools: https://amzn.to/3m9UhaN DISCLAIMER: This video and description contain affiliate links, which means that if you click on one of the product links, I will receive a small commission.
