555 IC Circuits & Datasheet

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 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 electronic circuit that uses a 556 (Dual timer) IC to produce a two-tone train horn sound effect. Equivalent circuit using two 555 timers (single timers) is given.

Timer kits are an ever popular item with the hobbyist. This uses a 555 timer IC and goes from 8 seconds to 8192 seconds.

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

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

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

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

This is an excellent kit for use as an introduction to electronics and circuit analysis. Seven LEDs arranged like a real die face. Push the switch and the die rolls and then slows down, stops. Ingenious circuit design used to minimize components. Uses 140

Drives any 5, 6 or 8 lead unipolar stepper motor. Based on the UCN5804 IC. All features of this IC
