Basics of Resistors. Design Note 5


RESISTOR

For a Beginner, identification of Resistors is a big problem. So byhearting the Colour code is essential. But some tricks are available to identify the resistors easily. A Resistor is a passive component inevitable in circuits to reduce the voltage and current in a particular section of circuit. Resistor is non polarized with two leads for connections.

How to make TSOP 1738 Circuits . Design Note 4


TSOP-1738-PINS

TSOP 1738 is the Infrared receiver Module widely used in remote control applications including TV. It is a versatile sensor that receives the coded Infrared pulses from the transmitter and directs the functions of the device. TSOP 1738 sensor is designed to receive IR rays pulsating in the 38 KHz and hence the number 1738. It has a circutry inside a black coloured filter case . The black coloured filter case prevents the effect of sunlight and other lights on the Photodiode present inside. There is a PIN Photodide inside the module which is the receiver of the Infrared rays from the transmitter. In addition to the Photodiode, there are signal amplifier, AGC ( Automatic Gain Control), output driver etc inside the module.
