Infra-red transmitter

Teaching Guidance for 14-16 PRACTICAL PHYISCS

To make the infrared transmitter you will need:

  • 75W resistor (from Rapid metal film resistor MR25 kit. 13-0270)
  • infrared-emitting diode SFH487
  • 3 mm LED clip (JPR 850-090)
  • socket 4 mm red (JPR 705-205)
  • socket 4 mm black (JPR 705-206)
  • halved square section 'plastic down pipe' approx 9 cm long (DIY store)
  • connecting wire

Assemble as shown in the diagram:
