hy Techrm. I want to tell you that you didn't give us the code
did you use any kind of solar panel and converted it to be used in IOT??
I used it here www.techrm.com/how-to-make-an-automatic-sprinkler-with-esp8266-controlled-by-arduino-cloud/
useless no explanation
The explanation is in the artiche www.techrm.com/solar-power-for-arduino-esp8266-and-iot-complete-guide-to-energy-independence/ as you can see in the description of the video.
@@techrmcom ok thanks
Good
Thank you
God is the almighty!
Crazy project stupid man😅
Hello techrm, I want to express my deepest gratitude for your sketch and guide! For weeks, I've been working on an IoT project that uses a motion sensor to detect movement, takes a picture, and sends it to a Telegram bot account. Initially, I had an ESP32-Cam board. Despite buying it from a reputable seller, it turned out to be defective. Probably a copy of a copy from the original, but stamping his brand on it. I spent over 24 hours troubleshooting, trying everything imaginable, before concluding I needed to buy a new and better board. You seem to be the only one who tailored this project specifically for this board-I searched extensively. Your sketch works flawlessly! Reading through it and executing the project, it's evident that someone with a great deal of expertise was behind it. Hence, a heartfelt thank you for sharing your work! Greetings from Germany.
Hi OLAVIBES, thank you for your kind words and your appreciation. I always try to be clear and exhaustive in every project I create. I also always try to be clear and useful to my readers. So your opinion is very welcome and pushes me to give more and more quality to the blog articles. Happy to have made you happy. If you want, you can sign up for the newsletter at this link www.techrm.com/contacts/
Nice work! We'd like to offer you some boards if you might need them in the upcoming content. (PCBWay Daisy)
Hi Daisy, thanks for the appreciation. I have already made some PCBs with PCBWay with excellent results. If I need more I will contact you. Thanks again
Would like to have a switch to on off the light
If you want to use it to turn on a light (preferably LED) you can connect it downstream of the MT 3608 DC/DC converter (to the Vout+ and Vout- terminals) by placing a simple switch on the Vout+ line.
Would you know if it stops charging if fully charged while continue to feed to the output until battery percent lowers?
@@plaga9000 during the day, when the solar panel produces energy, the charge controller decides how much of this energy should be used to charge the battery. Typically, it charges the battery to a certain “draw voltage” and then switches to a “float” mode to keep the battery fully charged without overcharging it. The current that doesn't go to the battery goes to power the load.
Cool project!
Thank you!
data not updated to thinkspeak
some comment ?
ok i have done everything as it described in the circuit and have uploaded the thermohyrgometer ino file and all necessary librarires. It's working, but the date is not correct, I am getting a -999 for temperature and -99 for humidity. please help.
why are you connecting two potentiometer lead to ground? shouldnt one of them goes to power?
What about the 1ma current limitation on the wiper? Wouldn't the LED be drawing more than that amount of current?
complimenti sia per i video che per la musica ( di questo in particolare ) :)
this sure can be done by using a analog write so why use this chip for that ?
Frank Lopez Hi Frank!Yes, of course you can do this by using an analog write but the purpose of this video wasn't to show how to fade a LED. We chose to fade a LED just to show you this digital potentiometer works. If you read our whole article, you will understand it better. If you are interested on, you can find it here techrm.blogspot.it/2015/02/how-to-control-digital-potentiometer.html.
can we use this for my project? what i want is to have the arduino keep track of the shaft like a pot would OR can i use this as a torque incremental device ? what i want is to use a current driver ic that senses if there's a current other then what it started with and IF it changes then the MCP41010 would increment the voltage to the motor so that it can handle the new load and this digital pot will put up the amps/current on that motor to make it stronger for the time that is needed and then after that it will drop the voltage back down to normal working Voltage and current? can this be done with this MCP41010 ?
Frank Lopez You can drive, of course, a motor using Arduino but, instead of MCP41010, you need something more powerful, for example this shield www.arduino.cc/en/Main/ArduinoMotorShieldR3
why that one does it have a digital pot? like mcp?
Frank Lopez The Arduino motorshield is driven by a PWM signal, so there is no need to use a digital potentiometer.
