Strobe lights are commonly used as emergency vehicle lights for visual warnings. Supply – 9v battery Police Flashing Strobe Light Circuit Using 555 The rate of flashing can be adjusted by varying the ON period and OFF period of the astable multivibrator. In the circuit, LED1 lights when the output pin has a LOW state, and LED2 lights when the output is in a HIGH state. The only difference is that one more LED is added in the circuit, which ON when the 555 output is in a low state. It has the same circuit as a simple LED flasher circuit using a 555 astable multivibrator. This alternate LED flasher consists of a pair of LEDs that blink alternately. Supply – 9v battery Alternating LED Flasher With 555 IC Circuit Diagram Then the rate of flash can easily be tuned Also, instead of using a fixed resistance value for R1 and R2, either one of the resistance can be replaced with a potentiometer. The flashing rate can be adjusted by varying the values of either resistors R1 or R2 or the capacitor C1. The Rate of flashing of the circuit can be calculated as,
Here circuit consists of an astable multivibrator using an NE555 timer IC, which generates a square wave. The circuit has an approximate ON state time of 0.94 Seconds and OFF state time of 0.47 Seconds. That is a periodic output of HIGH and LOW state sequences that ON and OFF the LED repeatedly. A simple blinking circuit is basically a circuit to continuously ON and OFF the light supply on a fixed time interval. Thank you for the guides.An LED flasher circuit can be used as an LED blinker, vehicle indicator light, signal flashlight, etc. I first started with 3 LEDs and then I added a 4th. If ((long)(millis() – waitUntilSwitch)>=0) is setting RED as 0 and BLUE as 1?

I am a tiro ,can you help me what wrong in my code at turn off the police lights,thank you. Leave comments below if you have Questions or other Example Ideas.ĭear James Lewis, I used your code to my IR control code ,the Police Lights can ruining and flash,īut i can not turn off some time,some time the pin 13 light on,some time the pin 11 light on ,some time pin 12 & 13 off. It makes it clearer to the reader that lines 46 and 48 are checking to see which LED is the active LED. This is why the #define statements were used at the top of the code. The if-statement on line 45 independently controls the strobing of the active LED. It makes sure to disable both LEDs before setting a state, so one does not get “stuck on.” The first if-statement (line 36) checks to see if it time to switch the active LED. The millis() loops should be self-explanatory, after reading the millis() multitasking tutorial. millis() if-statementsīoth of the millis() if-statements make use of millis() rollover handling, instead of trying to reset millis(). This variable determines the rate at for the currently strobing LED. This variable tracks the millis() value needed before switching between the Red and Blue LED. The #define statements are optional, but make the code easier to follow later on (Around line 46). Using a couple of #define statements, this variable tracks which LED should be strobing at a given time.

Each iteration of loop() will update the LEDs with a digitalWrite() based on this state variable. This allows logic inside the loop() to determine when the lights should be turned on or off. Instead of using digitalWrite() directly, “state” variables are used to determine the state (on or off) of each LED. WhichLED = !whichLED // toggle LED to strobe Toggle back and forth between the two LEDs Unsigned long waitUntilSwitch = switchDelay // seed initial waitĭigitalWrite(LED_Red, Red_State) // each iteration of loop() will set the IO pins,ĭigitalWrite(LED_Blue, Blue_State) // even if they don't change, that's okay Variable to see when we should swtich LEDs Seed the initial wait for the strobe effect Some delay values to change flashing behavior
