i have a challenge also to you. Blink a LED every 1 second continuously using a simple sketch with 3 lines of code using 2 functions only. Materials needed are Arduino uno, 220 ohms resistor and LED.

@joedgoh 17 дней назад

Your instruction is incomplete. Does it have to be custom function or a built-in function like a simple digitalWrtie and digitalRead will do?. Is it required to use millis because you posted it on this topic? By the way, using 220 ohms resistor on UNO R4's gpio when connecting to an LED is not advisable, as its max current is only 8mA. I might not be able to answer your challenge because I don't know anything. I just teach and share what I know. I don't challenge others just to prove that i am better than them, because I am not. Please teach me and the others how it is done. Thank you.

I have a question and its. How can use single Arduino. Into multiple sensors like. Developing home automation systems using RFiD,Light,Fans, and temp. Using 1 Arduino and mobile app

@joedgoh 2 месяца назад

Hi, your question is broad and cannot be answered directly here with a simple chat. It is a combination of concepts that you will learn in the future if you continue watching this series. Thank you

@vijaysulakhe5605 Месяц назад

My request... kindly make such videos for Pi Pico W....it has lot of resources... and students ( and we also) are very much cost conscious...I can have 3 Pi Pico at cost of one R4...£ $ € Rs matter...many thanks.

@joedgoh 25 дней назад

Hi. Thanks for your suggestion and I understand your concerns. However, as of now, I do not have any sponsor for R pi pico W. If it wasn't for SunFounder who provided me with the Arduino kit and sponsoring this series, I would not be producing videos anymore because it is hard and time consuming. I only do it on a part-time basis. Producing online lessons is also costly. When I have a spare time and/or sponsorships, I'll produce the R pi pico W series. Thank you for understanding! 😊

@KingKong-kk4bs 3 месяца назад

Hi sir, how do we use push button as trigger/ toggle the movement of servo with millis since usually I used delay?

@joedgoh 3 месяца назад

The same way as I have discussed in this lesson. How do you use it using delay by the way? Let me see your code first.. thanks

@sheekosheko 2 месяца назад

Excuse me sir. I would like to contact you

@user-ii8fq3le8i 3 месяца назад

Are there solutions to your challenge activities on the web?

@joedgoh 2 месяца назад

Hi, I'm sorry but I don't post the Challenge Activity on the web. Thank you for your support 😊

@alistaircook1997 3 месяца назад

when will we see your next lesson 13

@joedgoh 3 месяца назад

Hi Alistair, I'm sorry for not being able to produce lesson 13 this week. I've been out of the country since last week (Japan 😃 ). I will start lesson 13 by next week. Thanks for watching! :)
