Controlling the LEDs Now that the pins have been assigned, you can start putting together the different modules to make the circuit work. The first module we will make is the one driving the LEDs. We will call it “blinker.v”. module blinker ( input clk, input [3:0] delay, output reg [3:0] led, input reset, input pause ); reg [23:0] count = 24'b0; reg [2:0] pos = 3'b000; reg running = 1'b1; always
