This circuit uses a 555 timer as the bases of the touch switch. You can learn more about 555 timers in the Learning section on my site. When the plate is touched the 555 timer is triggered and the ...

You can simulate a switch by connecting and then disconnecting one of the battery leads from one of the LED leads. Switches in circuit diagrams are often represented by a break with a bent line, like ...

After successfully building the circuit, we took the project one step further by incorporating an Atmel ATtiny13 microcontroller. The code switches the LEDs on and off randomly for a flickering ...

Some 1.5 v LED flasher circuits are available on the internet and we like to ... a 470 ohm resistor while the buffer output is at +1.5 volts. When the buffer output switches to ground (zero volts) the ...

2). With the circuit values shown, R2 will drop a bit less than 5 V before D3 turns on. Prior to turn on, D2 remains back-biased and no current flows through the LED (D1). When the potential at ...

A switch is a device that opens or closes circuits ... but not infinite electrical resistance but it is a "good enough" insulator for LED circuits powered by a 6-volt battery pack.

If you're using switches with motion sensors or timers, the LED bulb may draw power from their circuits and emit a faint glow. Additionally, issues with the electrical wiring in your home or ...

I'd like to switch over to LED bulbs and was ... You can get 3-way LED bulbs that have two independent circuits, but they cost more. A dimmable bulb won't work, you need a bulb that has the ...

5. Place the components Once you've finished laying down the circuit connections and switches, place the components over the copper traces. "For LED circuits, you can simply tape the LEDs on to ...
