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 ...

The module can be preordered for $250 and comes with an LED strip, LED power supply, and LED extension cable. If you want both the module and the case, that bundle can be pre-ordered for $1,100 ...

The usual method is to use the Arduino’s analog pins to send PWM signals to the module. This lets you mix each color, giving you full control over the RGB LED. Meanwhile, the other (digital) option is ...

Here, Arduino’s (Uno R3) A4 (SDA) and A5 (SCK/SCL) pins are used for the I2C control, and the module is 3.3 V powered by the Arduino itself. It seems that external pull-up resistors for I2C lines are ...

If you're looking to add wireless communication to your project, the Arduino nRF24L01 module combo is one of the most reliable and cost-effective solutions available. Whether you're building a DIY spy ...

Arduino Nicla Sense Env is a new sensor module with temperature, humidity, and gas (TVOC, NO2, O3) sensing that follows the launch of the Arduino Nicla Sense ME (Motion & Environment) module over ...

Now we know how to set time in the module, let's use it with an LCD to make a simple clock. Material Required. Arduino Uno; DS1307 Module; LCD Display; I2C LCD Driver Module; After gathering the above ...
