If you like to build electronics projects, with Arduino, Raspberry Pi, ESP8266, ESP32, Raspberry Pi Pico or with STM32 based boards this channel is for you. In this channel, we build electronics projects using the powerful and low-cost boards that are available today. We also build projects that use Machine Vision using boards like OpenMV H7 or Pixy II. If you are a maker or if you want to learn how to make your own Arduino or Raspberry Pi projects subscribe and join us for weekly RU-vid videos!
We publish a new project or tutorial video twice a month!
Together we explore the fantastic world of DIY electronics. We develop our own hardware and software projects to improve our lives and learn something new. Don’t worry if you don’t know how to program. We provide easy to understand code and schematics to build your own projects quickly so be sure to join us!
Would it possible to use the DFplayer to play music on a loud speaker via AUX cord? Or does it only work if the DFplayer is powering the speaker itself?
Just a tip if you didn’t know or are new to high definition tft displays: Instead of clearing the screen for each loop or each time something is updated, just paint over it using a black rectangle and then print the new data. It is basically partial refresh and will DRASTICALLY improve performance.
Thank you for the great video. For the second PIR motion detect example, it can be simplified by using only one interrupt (digital pin 2) to control the led on/off. The following modified code works very well: #include "LowPower.h" #define PIRmotion 2 #define LedPin 13 void setup() { pinMode(LedPin,OUTPUT); pinMode(PIRmotion,INPUT); attachInterrupt(digitalPinToInterrupt(PIRmotion),OutputLED,CHANGE); } void loop() { LowPower.powerDown(SLEEP_FOREVER , ADC_OFF, BOD_OFF); } void OutputLED(){ digitalWrite(LedPin,digitalRead(PIRmotion)); }
UPS just lost my hard drive. I gave it to Geek Squad (at Best Buy) for a repair. Since Geek Squad could not fix onsite, they sent to Kentucky. The UPS driver never scanned the package (this was a month ago), it got lost, and now UPS can't find it. That's 1 Terabyte of data (years of files and photos) gone because of UPS incompetence. Geek Squad should've forced UPS to scan before leaving, to at least ensure some tracking. Because they didn't scan, it's not traceable. Don't EVER give your hard drive to Geek Squad, as this weak link (UPS) could destroy all your data. Get a hard drive fixed locally, on-site. Geek Squad’s fault and carelessness in this was a) Not making sure that UPS scanned my package, and b) Not tracking the progress of the shipment. They should’ve noted that the package did not arrive and then immediately filed a claim. Instead, the manager waited until my email - over three weeks after I dropped it off - to look into it. So the package could’ve gotten stolen or even more lost in the meantime. Absolutely irresponsible, top to bottom, both on the part of Geek Squad and UPS.
I can't get this program to compile. Spent hours troubling shooting but no luck. 'String getDayOfWeek(int)' previously defined here String getDayOfWeek(int i)
I used my ST7789 display with an ESP32 and a DHT22 sensor. That gives me the temperature in Celcius or Fahrenheit plus humidity. Since the ESP32 is a 3.3 volt device there is little chance of damaging the display and with proper coding can have the information available over WIFI. Now I can monitor the temperature and humidity outdoors without leaving my desk.
Your code is generating the following error: Compilation error: redefinition of 'Adafruit_ST7735 tft' and stops at line 14 Adafruit_ST7735 tft = Adafruit_ST7735(TFT_CS, TFT_DC, TFT_RST); I installed the Adafruit library ST7735 and ST7789, version 1.10.4 Any ideas please?
what is the SSH PLEAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAASSSSSSSSSSSSSSEEEEEEEEEEEEEEEEEEEEE HELPPPPPPPPPPPPPPPP MEEEEEEEEEEEEEEE HELP MEEEEEEEEEEEEEEEEE! WHAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
Can I ask for help? I dunno why but when I try to run the code it doesn't work, it says something about line 3 module not found, but i copied all of the necessary libraries needed. how do I fix that? ps. when i booted it up it worked and displayed a later date, but when I try to set the time it says File "D:\code.py", line 2, in <module> import board, busio, displayio ModuleNotFoundError: No module named 'board' how do I fix that??
