The LED’s brightness is controlled with analogWrite(), which varies the voltage to the LED based on the potentiometer’s value. The sensor value and corresponding LED brightness are printed to the ...

IR Sensor Pinout. The IR sensor has a 3-pin connector that interfaces it to the outside world. The connections are as follows: VCC is the power supply pin for the IR sensor which we connect to the 5V ...

a WS1218B addressable LED, rcwl-0516 microwave motion sensor and arduino nano stair lighting project. this uses the FastLED library to control the LEDs. It's easier to use the HSV (hue, saturation, ...

The block diagram of the motion sensor alarm is shown in Fig. 2. Fig. 1: Author’s prototype Fig. 2: Block diagram of motion sensor alarm Circuit and working. The circuit diagram of the motion sensor ...

We set the potentiometer pin as 0 (A0 on the Arduino Uno board), the CONTROL variable is the voltage that is used to cotrol the led brightness of the speed of the fan. In the setup() function the ...

It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot form a variable resistor, whose resistance varies depending on soil moisture. This variable resistor is connected in ...

Gather your materials, build your sound shield, wire your LED+AJI-s, then wire the motion sensor and servo. When you finished with the steps above, bring altogether and check your audio using the ...
