WebSep 27, 2024 · The code for the PIC is rather simple, with the following key features: Password protection. Armed or reset state. Laser trigger detection. Key detection. The first check that is made in the main program loop is if the security system is in the armed state. If it is, then the analog pin RA0 is read to see if the LDR has sufficient light falling ... WebSep 1, 2024 · This laser tripwire circuit triggers an alarm when the line of sight between the laser beam & the LDR is interrupted. The design of this circuit is based on a 555-timer IC. A photoresistor (LDR) is used to detect the laser light from the laser diode. The LDR & the 220Ohm resistor together form a voltage divider circuit. cowboys wide receivers 2022 depth chart
