- It has several output channels of 3.3V logic level control by means of turning on relays, lamps, cooling, heating, spa pump etc... also can also do variable PWM output on a couple of channels etc. Here in this demo, I've set it to 50Hz voltage mains frequency for light dimming, but you can set it to 1kHz or any other preferred frequency up to 40kHz.
The potential applications for it are limitless, upon customisation. - แนวปฏิบัติและการใช้ชีวิต
Where did you find documentation to program it? I have a HLK-V20 but can not find any documentation. Thanks.
DO you have a diagram available to show how you wired everything up for the pwm side of things?
@Paul Bellett Can give us an introduction on how to program it?
добрый день,где взять программу для програмирования hlk - v20?
Good afternoon, where can I get the program for programming hlk - v20?
The HLK-V20 can only be custom programmed in the Hi-Link factory in China, they actually did the programming for me for this TH-cam video. So it is best to contact them directly.
Hi @paul, Can this moudle recognize the voice from a distance of 15-20 feets?
15 feet would be its maximum from the tests that I've tried on it. It becomes less sensitive if there is additional background noise in the room, such as having a radio turned on.
@@paulbellett2442 Is there any way, we can operate it from 15-20 feets distance. Any circuits to increase good sensitivity in an ideal room conditions. Can you do a test video on that?
I'm expecting delivery of an ESP32-S3-Box in a couple of days. It can supposedly handle a lot of background room noise and also reach 15 to 20 metres, but will need to verify personally when it arrives if that is indeed the case.
How did you program it?
At this stage of the game, the Hi-Link factory choses to FLASH program it themselves, from the list of customised commands that I had sent them. You can also choose from a list of people, such as male, female, Asian or American accent etc...Overall, I was reasonably satisfied with the results, since your voice command can determine what you wish the microcontroller to do, such as high/low voltage output, frequency & PWM control, customised serial port messaging etc...
@@paulbellett2442 Does the Hi-Link factory program for money? What are the rates?
@@radiolis994 I'm the Hi-Link distributor in Australia, I had ordered 50 pcs from them, so for me it was free to do it, it cost me nothing probably because I made it worthwhile for them by ordering these in quantity. However I will ask my Hi-Link contact what they are prepared to do for just 1 or 2 samples?
@@paulbellett2442 Thanks.
@@radiolis994 Just got word back today from the Hi-Link factory just before they take a break for their New Year 2021 holidays. The custom voice commands programming and associated outputs can be done for free for anyone, but the production order must be a minimum of 200 pcs, otherwise its a $300 USD fee if you wanted way less than this quantity.
Documentation ?
These microchips have to be programmed. From factory they only come with 2 voice commands built in.
@@rohbags Do you know any guides on how to program it? I can't find anything useful in the internet.
@@thegeqable No I have not found a single document. The chip I have only speaks some Chinese on boot up, nothing like this demonstration. I am beginning to think it may need firmware flashed for the features seen in this demo.
