The Definitive Arduino Uno Pinout Diagram This tutorial shows how to use the output pin of arduino to control an led. we can apply this code to control on off any devices, even big machines. ※ note that: for devices machines that use a high power supply ( > 5v) and or high current consumption, we need to use a relay between output pin and devices machines see arduino relay. Arduino uno's pin a0 to a5 can work as the analog input. the analog input pin converts the voltage (between 0v and vcc ) into integer values (between 0 and 1023), called adc value or analog value. by connecting a pin of the photoresistor to an analog input pin, we can read the analog value from the pin by using analogread() function, and then we can know the light levels relatively.
использование Uart D0 D1 на Uno непонятки аппаратная платформа Arduino Connect arduino to pc via usb cable. open arduino ide, select the right board and port. copy the above code and open with arduino ide. click upload button on arduino ide to upload code to arduino. move your hand in front of sensor. see the change of led's state. Arduino is an open source electronics platform based on easy to use hardware and software. it's intended for anyone making interactive projects. arduino senses the environment by receiving inputs from many sensors, and affects its surroundings by controlling lights, motors, and other actuators. Let's see how a photoresistor react in light. build the circuit above and notice how led brightness change. the resistance value becomes smaller when there is much light in the room. so in the dark the led remains off because the resistance has become very big. the arduino will help us to reverse this situation, let's see how in next step. Explore, learn and share your arduino projects with the project hub, a community platform for makers and enthusiasts. find inspiration, guides and tutorials.
