A water level indicator detects and indicates the level of water in an overhead tank and relays the information back to a control panel to indicate whether the tank has a high or low water level.
In this tutorial, I am going to use the ULN2003 IC to create a simple, inexpensive water level...
The UNL2003 IC contains 7 High Voltage, High Current NPN Darlington Transistor Arrays each rated at 50V, 500mA in a 16-pin DIP package. You can connect the IC directly to a digital logic (like Arduino or Raspberry Pi, TTL or 5V CMOS device) without an external dropping resistor. This IC features...
Had some time this weekend and a desire to create something new and interesting, so went ahead and created an Arduino/NodeMCU based indoor dial thermometer. This device displays the temperature in degree centigrade on a D-Shaped Gauge as well as on a 7-Segment display.
In addition to that, it...
A Gothic Lantern is a captivating piece of lighting that brings the allure of the Victorian Era into your home. The lantern is adorned with ornate top and bottom ornaments, reminiscent of the Gothic style that was prevalent during the Victorian Era.
