Pin: Out Of Ic Lm317

This is a complete AM radio for the standard broadcast band, most of which is on a single IC. Other components, such as coils and variable capacitor to make a finished radio are included. The IC is the RF Amp, detector and AGC circuitry. The IC's output d

An extremely simple and cheap DC power supply with variable voltage (1.2-25 Volts) control. The circuit uses an LM317 integrated voltage regulator Ic.

This temperature meter uses a Harris 7106 IC as the heart of a low cost, accurate temperature meter. LCD 3-1/2 digit readout. All of the active circuits are in this one, versatile chip. In addition to temperature functions, the board includes an area for

Data sheet for the 7805 (LM7805), a compact IC 5v DC voltage regulator integrated circuit. This page further describes the 7805 and provides Datasheets for the IC device.

This kit uses the TDA2009 class AB audio amplifier IC for high quality stereo applications.

Simple schematic for a doorbell electronic circuit that produces a ding-dong sound when your visitors presses the door-bell button. Based on IC 8021-2.

A bit different from other kits. We supply the three basic components for you to make your own movement detector. Included is a PCB mounted fresnel lens, a PIR movement sensor and the latest movement IC just released. Eight pages of application notes show

Flashes five very bright LED's in any one of seven, user-selectable, patterns. A COB (chip-on-board) IC makes assembly very easy; the chip is supplied premounted on its own board and a motherboard contains the entire circuit. Operates on 3 volts DC, batte
