In this paper, a novel safety approach is presented to mitigate the risks associated with pressure cookers caused by lack of understanding, ignorance, and other factors. We’ll use a temperature sensor ...

Velostat Pressure Sensor: Velostat is a pressure-sensitive material that changes its resistance when pressure is applied. In this project, the Velostat sensor serves as the key element for detecting ...

Connect relays to digital output pins on whatever Arduino via appropriate isolation circuitry, starting at some pin (default 5), sequentially Set the start pin and number of relays at the top of the ...

The device operates on a 5V DC supply, with capacitors C1 and C2 filtering any ripples. The Arduino Nano serves as the controller. The PIR motion sensor detects human movement and transmits data to ...

In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...
