The relay module will need 5V from Arduino to power up and will get input from four different digital pins of the Arduino. Now let’s connect the relay module to your home appliance. Take the positive ...

If higher current loads are to be driven a PNP transistor can be added to the module's digital output. Here the addition of 2N3906 transistor controls an electro-magnetic relay (RL1) for driving ...

Flow Measurement: The flow sensor calculates the flow rate of water passing through it in liters per hour (L/hour). LCD Display: An LCD screen is used to display the current flow rate measured by the ...

Note: This is an extension of the pump relay project found here. This is a student project for ENGR114 at Portland Community College. Using MATLAB and an Arduino connected over serial, we will switch ...

Arduino Plant Watering Kit content: Arduino Nano RP2040 Connect board (ABX00053) with Raspberry Pi RP2040 MCU, ESP32 module for WiFi, and Bluetooth LE connectivity. Arduino Nano Screw Terminal Adapter ...

Arduino Due and the Ethernet shield W5100 have the microcontroller, which has enough GPIO pins for the 16 channel relay , or 2x 8-channel relay. Since Due does not have everyone, the prepared source ...
