Breadboard Layout

Pico W breadboard

Note:

  • 4K7 in this image is replaced with 6K8 (but if you already bought 4K7, that is fine)
  • Bend the IR LED to point in the same direction as the sensors
  • Ideally cut the front IR sensor (TSOP4838) to have shorter legs than the back one
  • Legendz is not shown here
  • GND and Vcc are switched on some screens - check yours carefully - wiring these backwards will destroy the screen instantly!
  • Check the pinout of your speaker module too
