@FriendlyWire18 күн бұрын
Hello! Yes, you can do that with a relay module. You connect the LED signal to the input of the relay, and on the contact side of the relay you can hen switch other devices. But be careful with this: line voltage is dangerous, and please only do this if you feel confident about it. If not, no worries: you can probably talk to a local makerspace or find a programmable timer solution. Let me know what you think, and be safe.

1st electronic "article" I looked at in 18 years. Immediately I new I was listening to a good lecturer. Thanks ! Well done. What I was looking for is a digital readout 0 to 360 degrees. The knob had to be attached to a pointer on a compass rose. I guess one needs to add BCD for 3.5 segment display. Can that pic do it ?
@FriendlyWire2 ай бұрын
Thank you, I am glad you liked the video! If you want to resolve the position in an absolute way then you need an "absolute" rotary encoder. These have more outputs than just A and B, of course, because they need to resolve the whole angular span. But I am not sure if that is always necessary: if you don't need the full 360 degrees, you could also use a potentiometer and measure the voltage at the wiper with a good analog-to-digital converter. Alternatively, you could use a gear with a 2:1 reduction to map 360 degrees to 180 degrees on the potentiometer. What is your target resolution for this project?
@ihadadream-itsgonenow2 ай бұрын
@@FriendlyWire Thanks for answering. I have created a web app. It converts the shadow azimuth obtained from a shadow stick (to be your potentiometer turning "cylindrical knob") at center of a 0 to 360 degrees azimuth dial (azimuth angle is from 0 degrees to shadow) to an associated target azimuth. 0 degrees on the dial does not necessarily meaning north pointer but any required azimuth as I turn the cardboard dial I actually cut out a pointer above the 0 degrees It's an upsidedown marker or teardrop I WANT YOUR IDEA TO DISPLAY THE TARGET AZIMUTH AS YOU CHANGE THE SHADOW WITH THE POTENTIOMETER (OR OTHER SOLUTION OF YOURS) THEN YOU HAVE A SHADOW SUN COMPASS ! (make nice plastic toy with display) I have an improved web app that I call SHARKY SHADOWS for shark spotting (and flares and drowning people etc) I learnt long ago you cannot be a PC OR PHONE programmer AND a microprocessor programmer at the same time, but I can help anyone who attempts it with atleast some javascript guidance.

how to change the code?
@FriendlyWire2 ай бұрын
Good question! Because this circuit does not use any microcontroller, the code is fixed and cannot be changed. If you want to change the code, you have to change the circuit. Have a look at the companion article on my website: www.friendlywire.com/projects/code-lock/ . In this article I explain how the schematic works, and after reading it you will have a pretty good idea of how you can change the code :) But if you are building this circuit and have the pushbuttons in a separate location, a simple way to change the code is this: leave all wires unchanged, and just move the location of the physical pushbuttons around. For example, switch the location of pushbutton A and C on your keypad, and all of a sudden it looks as if the code has been changed. Let me know if this helps or if you have additional questions, and thanks again for your interest & for your question! And, most importantly, have fun with electronics!

Have you tried that? Let me know if this helps. If not, I can explain more. Don't be discouraged by this. It is a normal experience, and I have had similar experiences, too.

@@FriendlyWire I actually did it. I didn't know 'shiftIn()' function actually works but it is quite tricky at timing. I just keep on believing on it that it'll work until it did and made me so happy. Also, for people reading this I don't recommend using breadboard I recommend soldering it in a temporary soldering board because breadboard can have a chance of loose connection of the resistors causing it to read different.
@FriendlyWire2 ай бұрын
@@yamitokyoo I'm glad that it works now, congratulations! Awesome job, and thank you for sharing!! Yes, the timing can be a bit tricky, in the sense that if you do the clock pulses too quickly it may be too fast for the shift register. This is why I run these examples here at 4MHz (effectively 1MHz with PICs) which is slow enough so we don't have to worry. I am glad you got it working on a PCB! I like breadboards because they are so flexible, but if you get a bad breadboard it can be extremely frustrating because of loose wires/bad connections. Glad it worked out! :)
