Led Interfacing With Arduino Circuit Diagram. The following image shows the circuit diagram of arduino at24c256 eeprom interface. In this tutorial we are going to interface a single color 8 8 led matrix with arduino and display a few characters in it.
Arduino uno power supply 5v jhd 162alcd 16x2lcd 100uf capacitor. Now let s learn interfacing of switch and arduino here we will use switch to take input signal to the microcontroller so that we will be able to interface more input devices to the microcontroller like sensors output as input to microcontroller. One can power or leave the back light pins.
Circuit diagram and explanation.
The pin the led is connected to void setup pinmode led output declare the led as an output void loop digitalwrite led high turn the led on delay 1000 wait for 1000 milliseconds 1 second digitalwrite led. We all know switch is an input device and used. In this tutorial i am going to create 3 chaser circuits using arduino and ic4017 decade counter. Connect anode of led to port 13 and cathode of led to ground pin you can see gnd pin just above port 13 as shown in circuit diagram with the resistor in between port 13 and anode of led.
