The 32*16 module size means that there are 32 LEDs in each row and 16 LEDs in each column. So there is a total of 512 numbers of LEDs present in each module unit. Enable: This pin is used to control the brightness of the LED panel, by giving a PWM pulse to it.A, B: These are called multiplex select pins.
They take digital input to select any multiplex rows. Shift clock (CLK), Store clock (SCLK) and Data: These are the normal shift register control pins.Here a shift register 74HC595 is used.Ĭomplete circuit diagram for P10 module with Arduino is given below: Note: Connect the Power terminal of the P10 module to 5V DC SMPS separately. It is recommended to connect a 5V, 3 Amp DC power supply to a single unit of P10 LED module. If you are planning to connect more numbers of the module, then increase your SMPS rating accordingly.Īfter the successful completion of the hardware setup, now it’s time to program Arduino. Complete code for this 10 Led Display Arduino along with the video is given at the end of this tutorial. The stepwise description of the code is given below.įirst of all, include all the dependent libraries in the program. Here we are using “DMD.h” Library for P10 led operations, download this library from here and install it in Arduino IDE.
After that include the library for “ TimerOne.h” which will be used for interrupt tasks. This library can be downloaded from here. Then, include all the required fonts library, in our case we are using “Arial Black font” for the display. In the next step, define the number of rows and columns for the LED display board. In our case we are using only one module, so ROW value and COLUMN value will be 1.
