Toggling my LED using any remote control

By

In the previous email, I was able to turn an LED on for one second using any remote control. Today, I expanded on that to toggle it instead.

So press any button once - LED turns ON.
Press any button again - LED turns OFF.
Press any button once again - LED turns ON.
...and so on.

The only change from last time is that I added a JK flip flop on the output. If both the J and the K inputs of a JK flip flop are high when the clock pulse comes, it toggles its output.

I didn't have time to solder and make it work with my electronic candle yet, but it's pretty cool just to be able to control an LED with any remote 😎

I'll continue the project in the show & tell section inside of Ohmify (for members only), but for the curious mind, here's the complete schematic:

May 3, 2024 | #589    Measure Gamma Rays with a Photodiode: Radiation Detector Using a BPW34 The first device that springs to mind when thinking about measuring radioactivity is the Geiger-Müller tube. However, these counter tubes can be difficult to find and expensive; and, even if you do manage to get hold of one, you will still need to find a way to generate its operating voltage of several hundred volts. It is less well known that even a humble photodiode such as the BPW34 can be used to detect X-rays and gamma radiation.   more...     The Andonstar AD210, an Affordable Digital Microscope with a 10.1" Display The Andonstar AD210 is an entry-level model digital microscope with a large 10.1...
