Housed in a signature Little Bird yellow case, this kit includes everything you need to build and code your own laser alarm system using a Raspberry Pi Pico.\n\n🔧 What’s Inside\n\n\n\nLittle Bird yellow case – portable, durable, and bright!\n\nRaspberry Pi Pico – the brains of your project\n\nLaser module – emits a bright 650 nm red beam\n\nLaser detector module – senses when the beam is broken\n\nBuzzer – sounds the alarm when triggered\n\nMicroUSB cable – connect and code your Pico\n\nAAA battery pack – powers your circuit\n\nAll you need to add is 2 x AAA batteries and a USB power bank or computer to power your pico. \n\n\n💡 What You’ll LearnLaser Module BasicsBuild a power pack, strip and crimp wires, and test your circuit safely.Discover how laser diodes work and learn essential safety practices — never look into the beam or point it at shiny surfaces!\n\nPico Trip Wire Project (Coding + Sensors)Combine hardware and software to make a working laser alarm.The Pico board already has the code to run this project loaded on it - you just need to plug in the components and watch it work!\n\nPlug the laser detector into GP2 and the buzzer into GP19.\nUse MicroPython in Thonny to program your Pico.\nWatch your code “see” the laser beam and trigger the buzzer when the beam breaks.\nDesign a 3D-printed enclosure in Tinkercad to prevent false triggers from sunlight.\n\n\nFind details of the code on our blog\n\n⚙️ Skills You’ll Build\n\nCircuit wiring and breadboard layout\nSafe soldering and wire crimping\nDigital input/output logic\nCoding with MicroPython\nSensor integration and debugging\nDesign thinking with 3D-printed enclosures\n\n🧭 Perfect For\n\nScouts and school STEM programs\nBeginners exploring coding and circuits\nMakers who love lasers, sensors, and sound\n\n🛠️ Pro Tips\n\nAlways check polarity — red = 3.3 V, black/blue = GND.\nLEDs only light one way (long leg = +).\nIf something doesn’t work, check wiring before the code.\nExperiment: swap one sensor for another and watch how your program adapts!\n\n🚨 Safety Reminder\nEven low-power lasers can damage eyes.Never point at mirrors, people, animals, or aircraft.Handle wires and tools carefully, and always work under supervision if you’re new to electronics.","vendor":"Little Bird","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":131,"title":"Default Title","sku":"LB-L-TRIP","price":19.0,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":103,"option1":"Default Title"}]}
