Raspberry Pi Pico - Alarm Clock Project

- This is a basic alarm clock made with the Raspberry Pi Pico and a few modules. The clock is based on the ds1302 RTC module, and display the date and time through the 16x2 character LCD.
If you have any questions let me know, and I appreciate your feedback as it helps me improve the content I put on the channel. Also thanks everyone for all the support.

If you are new to the Raspberry Pi Pico I have made a Getting started video:
• Raspberry Pi Pico Tuto...
Check out my channel for other videos on the Raspberry Pi Pico, as I will regularly upload tutorials and projects related to the Raspberry Pi Pico. - แนวปฏิบัติและการใช้ชีวิต
In the schematic diagram there is a small mistake, the CLK of the RTC is connected to ground and not GP18
I like the LEDs along the bottom! I use a similar lcd clock to time my work hours, but I used an esp8266 which connects to a time server via wifi to set itself, and 4 cherry keyboard switches and 3d printed case.
I saw a lot of people connecting the esp to pico for external wifi have not given it a try yet, it seems most people set the clock that why then you don't need the RTC.
I've been overthinking and under actioning a project like this for quite some time. The differences for the project in my head are
* to use a pico 2w
* allow the device to set it's own clock automatically via NTP
* allow for an API to flex the alarm time based on outside conditions (for example if a system is down, the alarm wakes you up, or if the weather is looking like your commute is predicted to take longer, then it wakes you up 30 minutes earlier to account for the longer commute). The idea is that the alarm clock could just accept the new alarm times via the API and pre-shared tokens/keys, but something else that holds the keys could be programmatically smarter to figure out the new alarm time. Another example that I thought would be cool was if, on a school snow day... I wouldn't have to sneak into my kid's bedrooms to turn off/change their alarms.
Great project! Awesome execution! Thank you for sharing with the community.
That does sound like a lot of work, my programming is not up to standard as it should be struggled hours just to get the formatting correct on screen, but have the clock connected to online and having connecting to an API to change alarm based on conditions sounds cool. I think to change the alarm in this project I made easiest might be to add a Bluetooth module to set the alarm instead of the buttons. Also thank you for taking the time to comment and I am glad you liked the project. I am making PCB's for this for my students so that I can have them build it on breadboard then give them a PCB, then they can focus on making their own case etc.
Nice. I wil make all your project. They were great
thank you
great vid! very explanatory!
Thank you
Awesome job!
Thank you👍
Super random comment, but I came across this video and noticed that it was uploaded on my birthday! :D I think this is telling me to build a Rasp Pi clock now lol
happy belated birthday, I think so. I made a pcb for it to do a version 2, which I should maybe do this weekend.
hi, im trying to make an alarm clock like the one with pico but i will be using a raspberry pi 4 is there any way to avoid using ds1307
Hi Nima, first question is will the Pi be connected to the internet if so, it will be much easier since you can access a website through API then get accurate info about weather etc. to display.
great project!, i want to set it like a temporizer... or set the alarm in a particular date... how can i do that?
You are going to have to write another function to set the date and if it the set date is equal to the date set by user the alarm will go off
Awesome! :)
Glad you like it!, for the next video suggest a decimal to binary converter 😉
@@NerdCaveYT Can you please do a video on a decimal to binary converter? :)
Could you build the alarm clock with the internal pico rtc?
The only problem using the internal RTC, is that the Pico does not have a battery on it, so every time it is turned off you will have to set the time where as with a RTC module it keeps the time as long as it has power, or if clock has access to Wi-Fi then Pico W is better since you can quickly grab time from online. If you want to use the internal RTC with micropython as follows:
rtc = machine.RTC()
rtc.datetime((2020, 1, 21, 2, 10, 32, 36, 0))
print(rtc.datetime())
Great job , i want to set 2 different alarm (06:00 and 17:00) how can i do????
The code will have to change for that to add two functions or to set two alarms
@@NerdCaveYT Can you help me to do it thanks ☺️
Would this work with a raspberry pi 3 too?
it would but the code shown here would not work, as you will have to use libraries specifically for the pi 3. I would also suggest not use the ds1302 if Pi has wifi because can get date and time from any website providing that info through there API
Is it possible to connect it to a 9v battery as a source?
No. Safe operating voltages are between 1.8V and 5.5V. If you want to I would suggest you get a buck converter module that will step 9V down to 5V or a voltage regulator.
If got light on the buttons you could also build a Simon Says Game :) congrats.
What a great idea did not even think about it, should add that to the code.
sir getting error in main file line 39 please help
so few things it could either be the connections to the pico or:
I2C_ADDR = 63
I2C_NUM_ROWS = 2
I2C_NUM_COLS = 16
which there is a chance that your I2C address is not correct.
I've had problems with DS1302 not showing correct time after 1 year
I have so far not experienced anything but then again the clock only been on few weeks
@@NerdCaveYT yeah. It's just a few min per year so not a big deal considering how cheap and accessible they are.
Btw I learn so much from your videos, keep up the great work!
@@MahBor thank you this long break from making videos was awful but settled in the new city so can't wait to start again
can you set the time?
The time you have to set in code unfortunately, you set the ds1302 time here: ds.date_time([2022, 5, 24, 0, 18, 24, 00]) then run the code then the ds1302 will start keeping the time then you have to uncomment the line of code and run the program again. This will then make sure the time is not reset but still using the correct time from the ds1302. That is why I only made the set alarm functionality because once time is set the battery on the ds1302 can last up to 20 years of keeping the correct time.
@@NerdCaveYT I see, thanks for the fast response, love the projects. Great job.
@@TheUnofficialMaker Thank You
How about an Amazon Echo Clock? Maybe with a Pico W, but probably with a Zero W.
I have not heard about Amazon Echo Clock before will check it out, recently I made a clock with the 8*32 rgb matrix using the pico W have not recorded the video yet
@@NerdCaveYT I just mean an Echo that also has a clock. I've seen builds for an echo, but not a combination one with an alarm clock 😉
@@pouceo I checked now what it is, we don't really have amazon back home and currently I am living in China so all the smart home things are xiaomi projects and of course all in chinese
@@NerdCaveYT ha! okay, thanks for looking into it.
@@NerdCaveYT My son and I are making him an alarm clock based on your build with a pico W. This way I can set the time pulling from the internet. I'll be interested to see your pico w build when it is finished.
This guy makes no sense! Is he speaking English? Why does he have a beard? This is insanity! 10/10
Take of your jacket right now
