Introduction: 10 LED Flasher

Picture of 10 LED Flasher

This instructable will show you how to make a super simple LED flasher. I was thinking about a mod where you could wire this up to an alarm circuit, and it would flash and make noise. If anyone figures it out, send me a PM or leave a comment.

Step 1: Parts

Use a Jumper Wire.

Step 6: Connect Pin 2 to Ground With the 10 UF Cap.

This capacitor is polarized, so be sure to connect the longer pin to pin 2.

Step 7: Connect Pins 4+8

Use a Jumper Wire. Once you connect them, connect pin 8 to +6V.

Step 8: Connect the + and - LED Terminals in Parallel

Connect positive to positive, and negative to negative.

Step 9: Connect the - Side of the LED's to Pin 3 and the + Side to +6V.

The LED's and the buzzer should switch on and off. If not, then check the circuit. Go through all the steps again and check your wiring.

It's just next NE555 led flasher circuit. There are lots of these in the internet and in the Instructables. Only change is you connect 10 leds in parallel instead of one. Nothing creative.
