"Near-Wavelength IR in Action Near-wavelength IR is a technology we use every day, but how it actually works in an embedded control application is fascinating. Jeff explains. He then makes use of LEGO’s sets of electronic components and other devices to build an IR-based controller for LEGO IR remote-controlled trains. Topics Discussed How does NR IR work in an embedded control application?How to build an IR-based controller for LEGO IR RC trains. Tech Used Heltec's HTIT-W8266 (WiFi-Kit-8) Espressif Systems' ESP 8266M5Stack's Atom module, I2C display, I2C joystick and IR transmitterTSAL6200, IR LED and TSOP38538 receiver from Vishay When we deal with communication, especially with wireless comms, we normally want it to reach as far as possible."
