Unfortunately, it's not as simple as picking a topic and quickly whipping up some circuit. More often than not, The original article was about an infrared sensor and parabolic reflector mounted to rotate on a steppermotor shaft. With computercontrolled An infraredsensitive photo Darlington transistor (GE L14F2) is mounted at the focus of a parabolic reflector, which is attached to the shaft of a stepper motor; the ultrasonic transducer is mounted above it. The infrared sensor and The infrared waves bounce off the glass and, if the angle is right, arrive at the television. Detecting. Infrared. Light. You can detect infrared light in an electronic circuit in several different ways, but the most common is with a device called a

To understand how a Figure 32shows a simple circuitthat uses an infrared phototransistor to detect infrared light. When infrared light is The simple infrared joystickcomputer interface described here links only one of the potentiometers in the joystick with a Color Computer. One way to link both potentiometers is to assemble two identical transmitters and receivers as suggested in Fig. 527. Use an 880nm LED for one transmitter and a 950 nm LED for the second transmitter. Replace the receiver pho todiodes with identical LEDs. In other words, the 880nm transmitter should be coupled with a receiver that uses an Figure 145:

Schematic.of the infrared detector. Did you ever want to see in the dark like a cat? Now you can, by building this simple infrared detector. The circuit uses just three parts (plus a battery). You can make the circuit a little fancier by adding an SPST (singlepole singlethrow) toggle switch between the + (positive) side of the battery and the phototransistor to turn the detector on and off; or you can go the simple route and just unplug the battery when you aren't using the detector.In this design, the lowest mechanical resonant frequency is above 10 kHz. Therefore, the gain and bandwidth of the electrical circuit used to control the sensor may be substantially larger than that used in typical STMs or in previous tunneling sensors.

Because.of this, the feedback circuitry for tunneling sensors may be very simple. A typical feedback circuit used to control the tunneling IR sensor is shown in Fig. 9. This circuit uses a single operational amplifier to produce correction In robotic games, competition platforms are well defined and uniform; therefore, simple infrared sensor pairs can be used to measure the distance, to sense objects, and even the hue of the object color. Figure 3.5 shows a typical arrangement of infrared emitter (D1) and photodiode (D2) receiver circuit used for detecting lines drawn on the competition platform. The transistor T1 is used for switching on IR emitter D1 when necessary. The resistor R4 provides means to compare light Aim a remote

The circuit needs to detect and stretch the received infrared pulses so that the output signal conforms to the standard serial data

It is important to ensure that the DTR Moreover, for simple onoff functions such as controlling a lamp or fan, we do not need very complex circuits. The IR remote control circuits using photo diodes and photo transistor sensors suffer from a major drawback of being affected by ambient light and a very low range. The IR remote control circuit described here can be used for any simple onoff function. The advantage is that matic diagrams of the transmitter and receiver sections are shown in Figs. 3 and 4, respectively.Infrared Circuits The sources of the following
