Seems like a block of code is put out there, then everyone does it exactly the same. I would use a different approach. Simply use one variable such as Blink Blink=millis()+Millisecond interval you desire. millis()+1000=every second. then just check if millis()>Blink IF yes then check if pin is high or low and take appropriate action with your IF ELSE, if high set low and if low set it high. Then just put Blink=millis()+1000 just before exiting your if statement when you checked if millis() was > Blink.
Thank you very much, it works now Was trying for around 8 hours, with different libraries and clients, and none of them worked, but finally, in the end, this works
I've been binging your videos. They are really nice and informative. May we also have a tutorial about RTOS? Along with interrupts, I think this is also a very good and must see for beginners like us since we are stuck in a somewhat "linear" flow of our programs for our projects. I'm subscribing, hoping to see more content from you especially other micro controllers like STM32 and ESP32 even tackle other peripherals/lines like CAN and DMA. Thanks for the video!
I received my SunFounder Ultimate Sensor Kit the other day and my Photoresistor Module only has 3 pins (VCC, Ground & DO). Can I get an updated sigmatic and code to use?
I really enjoy your teaching style. I have myself and my students using these tutorials for learning how to use sensors, LEDs, motors, sound and pneumatics for animatronics. You do an amazing job as a teacher. Thank you so much.
I'm using atmega and stepper driver for nema42. The problème I'm facing is big interférences wich disturbs arduino. Inputs become random even i use an external pullup resistor of 10k. The project works perfectly when the motor is off. How to fix EMI in this case. Note that in my project, i'm using two motors, a stepper nema42 and a 0.5kw 3 phase motor.
Hello, thank you for this beautiful video. I'm a novice and I'm stuck doing the exercise. in the example the on and off time of the LED is the same, if I code the same principle for another LED, the first LED also lights up even though it should not. the off time of the first LED must be longer than the on time so that the second LED can light up in turn, and I don't know which line of code to intervene. where is the answer to the solution and sorry for my broken english. thank you
Hi, need help. When I’m connecting my R4 Wi-Fi to my laptop, power and L Led are lighting up but windows is not detecting board and not assigned any com port. I’m using latest IDE and installed R4 board in it. What to do?
Excellent description of Analog and Digital sensors. I tried using "bmp.readTemperature(true);" for the BMP280 sensor to get the Fahrenheit reading (like we used "dht11.readTemperature(true);" for the DHT 11 sensor), but it didn't work. Oh well, thought I'd give it a shot. I've enjoyed both this series and the "Arduino UNO R4 Minima" lessons. I look forward to the next lesson(s). Thank you!
I love the video. It works great as long as i don't hold the button down for a bit. If I do, it interrupts when I finally release the button. Trying to find a way to prevent that.
Great series! I was originally looking for a series of lessons for the Arduino UNO R4 WiFi and found this one for the Minima. I purchased the "SunFounder Ultimate Sensor Kit with Arduino UNO R4 Minima" and have appreciated your lessons. I stumbled through some of the "Challenge" sections but worked through them. You provide enough hints to complete the challenges and made them interesting. I did go back a couple of times to a previous lesson to properly figure out the challenge and will keep these Sketches as references for future projects. I look forward to going through the "Arduino UNO R4 Wifi - IoT Development Crash Course". I do wish I could purchase the SunFounder Ultimate Sensor kits without the Arduino boards since I already have them, but its not enough to deter me from proceeding with the next series. Thank you!
Education is Life everything is beautiful. But I need a code to flash the LED on the web server. I have a D1 mini esp8266 and I don't know if the code will work with my esp... but I can try. I wrote to you at joedgoh........(e-mail)
I am still confused on how the multiple lights would be configured so only one comes on at a time. You left a clue about the pos=90 to display the green LED but I'm unclear on where that logic would be. Is there "challenge code" I can lookup to see how to handle this?
I need some help. The server can be accessed by clients on the local area network, but how can I deploy it to be accessed by my devices anywhere on earth through the internet? is there restrictions on the ESP to achieve this?
