Attach SEEED relay shield v2.1; Load Arduino Uno with include ino; Attach BMP180 sensor to Arduino (3.3V to VCC, GND to GND, SCL to A5, SDA to A4) Connect basic button to GND and D2 and LED to GND and ...

In emergency state (RED LED on) the Arduino waits for another 100 seconds for a valid command to leave emergency state. If no command is decoded the ATMega328 CPU (on the Arduino PRO Mini) is beeing ...

If so, remember to connect the VCC pin to 5V of the Arduino board to enable the control input pins IN1 and IN2. Also note at this point that, if you want perfect galvanic-isolation, do not link ...

Actually, Arduino and Bluetooth modules work with 5 volts supply. In the Arduino board, there is a voltage regulator to maintain the voltage. In this project we are dealing with an Alternating Current ...

Abstract: This paper aims to design a digital overcurrent relay with a characteristic of a standard inverse that can comply to the IEC standard 60255. The overcurrent relay which is used to protect ...
