Diy Easy Arduino Laser Tripwire Security System Youtube Step 3: connecting the laser and sensor to the arduino. starting off with the sensor, the pins should be connected like this: sensor arduino. gnd → gnd. out → pin 2. vcc → 5v. and now the laser module: laser arduino. In this video i will teach you how to set up your own laser tripwire home security system!patreon: patreon rgbfreakinstructables: www .
Diy Easy Arduino Laser Tripwire Security System 4 Steps With The led will go into gnd and pin 13 of the arduino. i provided a image with all pins tagged to make things easier for you. step 3: connecting the laser and sensor to the arduino . starting off with the sensor, the pins should be connected like this: sensor – arduino gnd → gnd out → pin 2 vcc → 5v. and now the laser module: laser – arduino. 1 step 1: aligning the laser modules. 2 step 2: connecting the speaker and led to the arduino. 3 step 3: connecting the laser and sensor to the arduino. 4 step 4: program your arduino. in this tutorial i will be teaching you how you can build your own laser tripwire security system at home! you will need the following components and materials. Trip wire red dot laser diode. alarm buzzer. sensor photoresistor. power supply 9v battery. wire male to female breadboard jumper cable. resistor 10k. i used an improvised laser diode that was placed on a breadboard that was powered by a 9v battery. alternatively, a laser pointer will also work well for this project. Step 4: the code. before you use the actual code for the alarm, use the analogread code for getting the values of the ldr while the laser is incident on it. use this as the threshold value in the alarm code. const int buzzerpin = 9; int led = 3; void setup() {. serial.begin(9600); pinmode(buzzerpin, output); pinmode(led, output);.

The wiring is simple: power the driver at 5v. connect the laser diode anode and cathode to the ld and ld terminals. modulate using the mode pin connect it to an arduino digital output. the wld3343 then handles powering the laser diode correctly and modulating it at 4khz for the tripwire alarm. First mount the alarm circuit in place. then mount the laser pointer to the opposite side. carefully adjust the position of the laser pointer so that it is pointed directly at the photoresistor. once you have the light from the laser pointer centered on the photoresistor, you are ready to arm the alarm.
