Flashing LED Circuits

You can do all sorts of cool things with these flashing Light Emitting Diode (LED) circuits.

An LED circuit that alternately flashes two LED's on and off. Perfect for a hazard or warning sign. When one LED is on the other is off.

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 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
