2N2/6 Schematic Diagrams

Many individuals use headphones connected to a computer sound card output to enjoy music or games. It is common for these headphones and microphones to connect to the appropriate slots on the sound card. However, if the female plug...

The circuit is a relay delay pull transistor configuration. Initially, when powered, the 16 µF capacitor has a voltage of zero, resulting in both transistors being off, and the relay remains inactive. As the 16 µF capacitor charges over...

The two circuits below illustrate generating low frequency sinewaves by shifting the phase of the signal through an RC network so that oscillation occurs where the total phase shift is 360 degrees. The transistor circuit on the right produces...

This timer is intended for individuals seeking to achieve a tan while minimizing excessive exposure to sunlight. A rotary switch adjusts the timer based on six categorized photo-types. A photoresistor modifies the preset time value in relation to sunlight...

This circuit was designed for an audio amplifier project to control the speaker output relay. The primary function of this circuit is to manage the relay that activates the speaker output in the audio amplifier. The circuit introduces a...

The schematic for an infrared burglar alarm circuit is depicted in Figure 1. The infrared transmitter operates as a multivibrator with an oscillation frequency of 40 kHz, utilizing the NE555 integrated circuit (IC2), along with resistors R1 and R2...
