2.93 IR control
Circuit 198:
Infrared transmitter
Setup information
Install the diode and the resistor as shown in
Fig. 2.198
followed by the jumper wire. Check the placement
on the board again and only then connect the battery.
Components required:
1 x IR diode, 1 x 1 k
Ω
resis-
tor, 1 x breadboard, 1 x 9V
battery with clip connector

Infrared transmitter
Experiment
If everything is wired correctly, the IR diode emits a strong light within the infrared range. This light is invis-
ible to the human eye; therefore, we will introduce a suitable photoreceiver in our next experiment.
The circuit diagram for this experiment is shown in Chap. 3, Fig. 3.198.
