Hi Joed, can’t wait to learn from your next lesson.

[philgirard]

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

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.

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 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

[vijaysulakhe]

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.

Hi prof! Can you do a video tutorial for PUG xml and ruby on rails?

[KingKong-kkbs]

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

[sheekosheko]

Excuse me sir. I would like to contact you

[iifqlei]

Are there solutions to your challenge activities on the web?

Hi Joed,
I installed avr boards 1.0.5 as per your video. However it’s not finding <PWMServo.h>.
