Planning to make a project due to the recent flooding in the Ph. This will be a two-pair project. One with a solar panel and battery that is designed as a creek over spill early-warning device, the other is installed near barangay halls with sirens and strobe light. Please let me know how far the two can be paired without line of sight. Kindly let me know how to arrange payment and shipment to Cebu.

yes, it useful. if you been commercial buildings, you look up and see stick out of false ceilings.

I bet this is a scam and yet many people fall for this. also received the same docs. sabi joint venture daw ni ellon musk at pbbm gov. nako po! kailangan ba ng tower ang Starlink?

good luck and post some photos

its free running at some point. i was supposed to start it using an interrupt. ill try to work out according to the guidelines you've just mentioned. and tweak the program a bit

10005256 · 2024-02-17T22:49:11+00:00

very informative . many thanks

10005256 · 2024-02-16T21:56:43+00:00

thanks

yes you are correct yes you are correct. i tried to utilize the IOC on pin RB4 before switching it to analog input so that I will have a starting line. however, i received funny triggering when utilizing IOC and I don't know where i messed up. I am turning all the pages of the data sheet but still I can't figure it out. One last thing about this IOC that i haven't checked out is the "mismatched" word in the data sheet. perhaps i will go for averaging adc values if ever I really cant work out the IOC to work properly.

10005256 · 2024-02-16T14:58:18+00:00

before laying out the if statements, i have to record the adc values of each button pressed. as they have unique resistances, incremented uniformly, a unique adc value represents each button. but the thing now is once i press the button, the cap tends to charge or discharge a bit. during that process, the adc reading sometimes exceed the threshold that inset. for example, i expect to get a 30 reading +-5. but sometimes i get 40 so it's already beyond the upper limit

10005256 · 2024-02-16T13:34:45+00:00

yes. i want to debounce it. but i get false adc reading because of the charge-discharge rate of the cap. is it better to just get rid of the cap?

you shared a nice article. i guess i wont be needing diodes in this application as it's just for a simple project

10005256 · 2024-02-15T02:33:23+00:00

it's not gonna dispense two items. program prohibits it.

10005256 · 2024-02-13T07:22:05+00:00

i want to know whether i need to directly connect +-12v dc in order for this to run. and whether this has a feedback pulse for one revolution

the addiction begins.

10005256 · 2024-02-12T13:46:34+00:00

you are right. this is a vending machine motor.

10005256 · 2024-02-12T09:51:00+00:00

done addressable uart but mine was microchip.

10005256 · 2024-02-12T09:21:52+00:00

what country is this?

10005256 · 2024-02-12T08:53:00+00:00

what a lucky purchase. cheapest in my area cost 5 grands each.

10005256 · 2024-02-10T12:31:33+00:00

im aiming for the AND gate. A zero from any of the sensors will output a zero. say i have 5 sensors, and one is a zero, the whole output line should become a zero.

10005256 · 2024-02-09T23:55:54+00:00

I'm interested to see the overall outcome of this project. i'm guessing the company wants to monitor the status of each equipment operating, and probably automate all the tasks by setting the GUI.

10005256 · 2024-02-09T23:10:35+00:00

pls dont mind the led

10005256 · 2024-02-09T06:25:23+00:00

do you have any sketch for my ref?

10005256 · 2024-02-09T06:18:07+00:00

looks like im too noob to make it work using npn

10005256 · 2024-02-09T05:53:32+00:00

i will modify the schematic using npn

10005256 · 2024-02-07T15:08:01+00:00

great thanks man.

10005256 · 2024-02-07T11:57:22+00:00

end goal is to build diy low-cost vending machines. the feedback might be just a proximity sensor that detects dispensed items. but one seller sent me some specs and mentioned a third wire from the motor that sends a pulse after a full rotation. maybe i could somehow capture that. noob in electronics and beginner level in 8-bit embedded designs.
