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:
Keep On Soldering!
