Imposter Attack – Among Us-themed infrared game made with ESP32 and MicroPython

Ian Langworth shares his journey of creating a laser tag-style game using the ESP32 microprocessor, inspired by a ride at Legoland California. He highlights the accessibility of technology and the fun of game development, which motivated him to explore programming and hardware. After discovering the ESP32's capabilities, including its dual-core CPU and wireless communication features, he began experimenting with various projects, including automating home devices. Langworth transitioned from Arduino to MicroPython for its ease of use, which allowed for quicker iterations and over-the-air updates for his devices. He detailed the challenges of sending and receiving infrared signals for the game, using inexpensive laser tag guns and a wand for gameplay. The design included multiple targets that would light up and react to player interactions, utilizing UV and white LEDs for visual effects. He also addressed power supply concerns, opting for rechargeable 18650 batteries and incorporating a protection circuit. To enhance communication between devices, he implemented ESP-NOW, a low-power protocol that improved efficiency. Overall, Langworth's project reflects a blend of creativity, technical exploration, and the joy of building something novel.
