- Arduinos are great for building projects, but it's important to take care of them when not in use. This video will show you how to reduce power consumption on your Arduino projects by using sleep mode, so you can save your batteries!
We also get to understand how the parts we choose for projects, affect the overall effiency of the final build. We do this by making little changes to an arduino pro mini. Truly fascinating, take a look
Hope you learn something new. cheers!!!

Awesome video! As someone fairly new to electronics this was super helpful and easy to follow 10/10
Glad this was helpful. This channel was started to do just what you've described.
Im happy you found this video useful
Very simple, easy to understand explanation! Thank you for your tutorial, It's a lot of helps...😊
Feedback like yours is why i find time to keep making videos.
You rock. Much love my friend🍻
Please dont forget to subscribe.
💪🏽Great video. Very helpful👏
Glad it was helpful!
Have a good one.
Great video and beautiful kitty!
Thank you so much.
Please dont forget to subscribe. Cheers!!
Excellent tutorial! If you replaced the delay with LowPower of 2 seconds the current drawn When awake is reduced even further.
Interesting idea. I'd try this sometime.
Thanks for the feedback. Please dont forget to subscribe
Great Info... Thanks
You're welcome
on ESP32 I was able to get into 4uA but that is bare, without LDO. Still, my sensors (WiFi enabled) can last now for about 10-12 months on 1000mAh battery and I find it quite enough. Super nice explanation here
Awesome.
Im glad you find this helpful.
What parameters are you sensing/what does your esp project do if i may ask?
Happy new year fam. Cheers!!
@@Delali temperature, humidity (sht31), light (tsl2561) - that all do, including measuring the battery voltage and % (max17048)
some also have motion sensor built in
other sensors that don't sleep also CO2
all of them feed data to Home Assistant over ESPnow through the ESPnow2MQTT gateway
Hi, which model of esp do you use ? Iam trying with the esp wrover-e but in deep sleep mode consume 40uA…
@@fabirodriguez3677 ESP32-S2-WROOM-I is 20uA, ESP32S-WROOM-32D is 4uA
Do you have an email to ask you any questions? because I have the esp32 wroom-32 and the consumption is higher. The only one I found to buy is the esp32 wroom-32d
I can sleep arduino over 8 seconds? An example … 15 or 60 minutes?
You are reading the current between the new regulator and pro mini (VOUT), should you not have put the multimeter on the VIN line of the regulator to include the quiescent current of the new regulator or doesn’t it matter?
I desoldered the old/original pro mini regulator. so i didnt have to use the VIN pin.
Also i directly connected the output of the new regulator to the VCC line.
@@Delali yes but you are not including the new regulators quiescent current as your meter is placed after the regulator? Isn’t it? I may have got it wrong but I’m sure that’s how your schematic had it.
Hello from Sweden. My question is if this sleep mode can be implemented also when the Arduino is waiting for a signal from a sensor to start a servo?
Best regards
Tore
Hello there,
It depends on the sensor, if the sensors output is just a HIGHor LOW signal, then you can put the board to sleep and use interrupts to wake the board when the sensor pin changes state for instance.
@@Delali Thanks for answer.
I solved this case with a relay with timer. So when button pressed it starts the relay that starts the controller for running the sketch.
When relay is timed out all power will be of and no battery consumption.
Next project will be an electric scooter provided with support wheel that keeps the scooter upright based on an angle sensor.
Regards
Tore
16 to 86 days is incredible. How do I connect the Twitter bird to the power supply😵
hahaha...
i'd make another video on how to connect the bird😊
08:34 You reduced the current draw by around 60%. Why did the battery lifetime only increase by a much smaller percentage? Thanks
Great question. I was surprised as you are.
I found out battery duration doesnt increase so drastically once current consumption is in the low uA range already. This is especially true if the difference isnt day and night huge.
The 60% reduction is only for the current draw while in sleep mode. The two second LED blink is what draws the vast majority of the current within each 10 second period, and that didn’t decrease so much
can you put arduino to sleep/awake using button instead of sleep time ?
Sure can. instead of LowPower.powerDown(SLEEP_8S, ADC_OFF, BOD_OFF);
you'd have to use LowPower.powerDown(SLEEP_FOREVER, ADC_OFF, BOD_OFF);
You'd have to put the above line of code into the code for button press. Also you'd have to use an interrupt to detect the button press and wake up the board.
I'd be making a video soon on this. Make sure to stay subscribed
When does this video come out?
04:55 Why didn't you just disable the LED in code, rather than desolder the whole component?
The LED i desoldered is the power indicator LED connected to VCC directly. Its not connected to a digital pin.
@@Delali Thanks! I'm excited to try my own low power Arduino projects!
How is your Arduino working with 0.7uA ?
Not 0.7uA.....its actually 7uA
I like your 🐱🐱
Thanks fam❤️
