- This video will describe a remote wireless alarm circuit where battery life is a priority. The concept of a zero quiescent current circuit can be implemented in your own project.

Great video! Videos like these show how endless the possibilities are to make all kinds of cool devices.
Glad you liked it!
Great video, you are one of the gems of the yt maker community
Appreciate that!
Yeah I agree, always high quality and detailed explanations, very instructional and done with care.
Lovely circuit. Thank you - great work! 👍😃
You're welcome!
thanks for the concise info, I hope your channel will grow bigger
Thanks for watching!
Nice Vid. I love making Arduino projects and the inspiration you get from other people. Thanks
You're welcome.
Superb. Succinct, encompassing, content; with a truly useful bent.
Glad you enjoyed it!
Hello nice project! Any possible projects on a remote car starter? Also would using a 555timer as chip be the cheapest for this?
I assume there is no bootloader as that would cause the switch to be held longer ? You have the most integrated channel, microcontrollers, digital, analog, discrete circuits and radio. It's the best !
The program is written in Forth so it is basically running assembler on bootup, no bootloader.
If the boot time is a problem a capacitor across the switch will give a longer hold time.
Thanks for the feedback!
Very nice
Thanks
This is a wonderful project. Is there a way to modify this to become a driveway alarm with multiple transmitters using a motion or microwave radar sensor to one receiver? I’ve tried store bought driveway alarms before but they seem to be unreliable with the distance of my driveway. Thanks.
Yes .. you can setup multiple transmitters as sensors targeting one receiver using Fixed mode. Check out this video on Point to Multi-point : czcams.com/video/JvBC7cEgI0E/video.html

Happy Sunday, would an LDR be considered a zero current device to use in this circuit as a switch?
An LDR never really shuts off completely. A photo-transistor would be a better choice.
When Vin goes high and arduino powers on, is it correct that the switch (i.e. alarm input) needs to be on for long enough for the Arduino to essentially boot up and bring D13 high? That means the binary alarm input can not be extremely quick, like microseconds (or milliseconds)? How long does that D13 take to go high after Arduino is powered on, compared to e.g. the length of time that vandal resistant piezo switch makes the circuit? (Or maybe I misunderstood how that latch works?)
The ATmega328p microcontroller on the Nano has been erased and re-programmed with a Forth operating system written in assembler. The Nano is not an "Arduino" so there is no bootloader. The vandal proof switch puts out a 100 msec pulse which is enough time for the micro to boot-up and turn on the MOSFET. If you need more time a capacitor can be put across the switch or for very short triggers a monostable or flip-flop latch can be used to drive the circuit. This circuit was used in a slide fence detector where the switch stays closed after the slide fence is tripped.
@@0033mer thanks for the response. In fact it’s one of those responses that can send someone down a rabbit hole :) O didn’t know about Forth, just learning about it now.
Check out Forth running on a multi-core microcontroller. czcams.com/video/KJoS9O5DYzM/video.html
Would you consider doing a simple code lock circuit using a 555 timer and/or transistors with push buttons? Thanks for your fine videos.
AT Tiny might be another IC to use instead of 555.
Check out this video for a very simple lock circuit.

Great Vid! 👍👍😉 What programming language is that? Lua?
The programming language is Forth.
It's FORTH language. You car find here a version for ARDUINO: arduino-forth.com/article/FORTH_FlashForth_installation_installerFlashForth
Thanks for this video. Using that particular circuit what is the total current draw when triggered?
It would be the current sum of the Nano and the LoRa radio. The current draw of the LoRa radio varies depending on the output power configuration.
Awesomeness.
Thanks!
Very cool, thank you
Very welcome
Hello sir. May you share the code? I want to try this simple alarm system for long range ( 20km) without power amplifier, my hobby is to build high gain antennas. I am not good at writing codes at all. I want to try how this alarm will work with my antenna and will share the results. Last summer with cheap $15 pmr446 radio I did 50km. Thank you
Code starts at 6:00.
@@0033mer Thank you sir. I can do that, the antenna is build and set up, 10db. What can I do for the receiver end? Probably again LoRa plus Nano? From the receiver end I will have unlimited power supply for sure. Thank you for your help
Hello. Is it possible to have the complete FORTH source code? Your work is great.
Forth code starts at 6:03
@@0033mer I am starting to take a very close interest in the LoRa system for ARDUINO. I think it is the most suitable IoT solution for communicating arrangements. Your videos are proof that it is doable. The FORTH language has a certain future for this type of assembly. I have some ideas for that. But since I wouldn't want to reinvent the wheel, I'm interested in your code that communicates between the ARDUINO board and the LoRa transmitter.
@@0033mer Also on my site, the characteristics of the LoRa transmitter arduino-forth.com/article/composants_LoraREYAX
To communicate with REYAX LoRa radio modules you have to use AT commands similar to communicating with the old dial up modems. czcams.com/video/jON3zbZY7ls/video.html
@@0033mer I have see all your videos about LoRa technology. In the video "Reyax LoRa Radio Link", it's give no explanation about >REYAX, no source code...
