The touch dimmer is built around 8-pin CMOS IC TT8486A/TT6061A specifically manufactured for touch dimmer switches applications. Since the IC is highly sensitive, use a long wire to connect the IC to ...

The circuit illustrates the function of a switch that responds sensitively by means of a touching mechanism with the utilization of two CMOS with models 4027 and 4011. JK Flip Flop – the most ...

There seems to be nothing a 555 can’t do. We’ve seen it before, but [electronzapdotcom] reminds us you can use a 555 and a few parts to make a reasonable touch switch in this video, embedded below.

Take a quick look at most older appliances, consumer products, and even medical devices of just a few decades ago and you’ll see their user front panels are covered with traditional, protruding ...

Experimenting with batteries, bulbs, buzzers, switches and other electrical components is a great way to learn about circuits and start to think about how to incorporate sounds into your Build a ...
