If we want to read the voltage that's going through the first resistor in the circuit, shouldn't we be putting the wire plugged into A3 in the same column as the 5V and first leg of the resistor? But when I do that it reads 5 volts and not the expected. I think I'm putting the A3 wire in the wrong place since the reading for my second voltage is correct.

I think I'm legend. You are using both power rails as 5V, but the top one on the power supply is 3.3V.

Like the slope of a line as Paul noted, however I simply used servoAngle=potVal/5.69 and appeared to get same outcome.

Hi Paul. I would like to do these lessons with the newer updated Raspberry Pi-5. Do you have any plans or suggestions using the Raspberry Pi-5? Thank you.

I used the != Comparison to turn it off

i love this man

Thank you so much

Another great tutorial. I have now also started to follow the Fusion 360 tutorials, which are explained better by you from the basics. Others immediately start with 3D drawings and the learning curve is, at least for me, too steep.

well explained sir...I am not CS guy but understanding in first go with Python

That was easy, I thought. Nope. And to add to my misery I cannot find any basket weaving courses in my neighbourhood... so I will have to keep trying.

thanks for great lesson

Paul, you are a Legend!!!

Well, I folded on the homework assignment from lesson 24. Even though, I went through setting up a toggle switch from your prior Arduino Uno tutorials and more recently on your Raspberry Pi tutorials, I have trouble understanding the coding to the point of being able to set it up on my own without copying it. Maybe your upcoming tutorial(25) will explain it in a way to "sink in" so to speak.

¡Gracias!

I am back to Pauls videos after completing the arduino videos 2 years ago, how i miss this!

i have not started working yet maybe i will start working 5 years later and only then will i support your patreon and buy one of the arduino kits for now i am just using simulators which are not convinient

Paul McWhorter, you are a person rich in qualities and amazing

Didn't quite understand why set Spin to High when it is an input pin, for the purpose of bringing up the pullup reistor, if someone can explain i'd be much grateful!

Great content, Paul! Here is my solution to our homework assignment: ua-cam.com/video/OG41VwhX_zQ/v-deo.html. Thank you for all your efforts!

I upload a video, after a while both the comments and the video are deleted, I don't understand why.I did it twice and the same thing happened.

i literally lost all sanity trying to complete the challenge. i was trying to use "!" as not (like in arduino) and didnt realize you simply type "not". i had to cheat and use google to find that out. otherwise my code was correct. i had also tried to do the alternate way via the if statements but it wouldnt work no matter how i modulated the code, i think it might have something to do with the fact that im currently running nano 7.2 or perhaps some other change in python/pi that im not aware of.

Man! This is great.

So glad I found this! Thanks!

Why do you need to connect a ground to the power rail next to the powermodule

I did my homework Mr McWorther, though my math is a little bit different from yours.

My homework: ua-cam.com/video/P4VwjfkM2Cg/v-deo.html

as usual, your video's are very good. one thing you may want to point out is an issue I had from the get go. My PICO would not show up in "this PC' I tried 3 different cables and even tried another computer. I went to the PI forums and did a search for 'Bootsel' it turns out this is very common to have cables that are for charging only and not for data. One of the posts said he had tried several cables before finding a good DATA cable. I dug around and found more micro-USB cables, and wouldn't you know the 4th one was the charm.

If you going to cust

I did it!

Loving this series! Still going through all your videos and re-watching a few of them to make sure I understand everything. Can you post an amazon link or production description for your "pookie" please?

This is a great approach to teaching. Comes with skill and experience compared to the garbage being advertised online lately. All bogus guys can only do foundation, none of their nonsense is enough to horn a skill from. None of them ends up teaching one to complete a practical project after all payments. Thanks Paul, this is great despite being 3 years (3 tears) old.

I am a Legend drinking rooibos tea

Pulled pot and added flex wire to ADC and flex wire to negative rail and tested batteries >= 3 volts.

Here's a comment about my homework without a link in case the other one gets deleted. I've found another IR receiver so I've made a video in case anyone is interested.

Once again, was tougher than I expected lol. I thought my code was going to be pretty good till I saw yours :( Here's my code: #include <Stepper.h> int stepsPerRevolution = 2048; Stepper myStepper(stepsPerRevolution, 2, 4, 3, 5); int motSpeed = 10; int dt = 50; int buttonPin = 8; int buttonVal; int toggle = 0; int oldVal = 1; void setup() { Serial.begin(9600); myStepper.setSpeed(motSpeed); pinMode(buttonPin, INPUT_PULLUP); } void loop() { buttonVal = digitalRead(buttonPin); if (oldVal == 0 && buttonVal == 1) { toggle = !toggle; } if (toggle == 1) { myStepper.step(stepsPerRevolution / 100); } else { myStepper.step(-stepsPerRevolution/ 100); } oldVal = buttonVal; }

I've found another IR receiver so I've managed to do my homework. ua-cam.com/video/leKFb0Q6Q8M/v-deo.htmlsi=HOO0GuWj2hYqld7f

Thanks you Paul. This is the best course intro I have ever seen!

Ur a true legend sir

Hi Paul. I followed your 2019 explanation of Low Pass filters (9 axis IMU) so I’ve been using them since we started with the 6050. Here’s the latest instance (Lesson 46 homework) ua-cam.com/video/pw6EfK6vdss/v-deo.html And, since you asked, I am not weary of this sensor yet. We haven't even touched on the gyroscope functions. I imagine that's next. A MEMS gyroscope !! That will be interesting. I wouldn't be surprised if the gyro brought back some of the 'snap' you're looking for. Thanks Paul

I have Python 3.6.9 setup and am getting an error 'Could not find a version that satisfies the requirement Adafruit-Blinka' dring the adafruit-circuitpython-servokit installation. Please can someone help?

I can't see anything less than that flashing from machine import Pin from time import sleep myLED=Pin('LED',Pin.OUT) while True: myLED.toggle() sleep(.017)

Great explanation! I'm just wondering if you could use two 330R resistors to get the same results as only using one 1K?

Yeah folded up. Didn’t see the wave coming. But I actually discovered that the color vector goes beyond 1. There is no limit to the number but around 2.5-3 it just gets very bright and then doesn’t really gets any brighter. So if you want a really bright object - there you go. Update: I used your technique for getting the brightness right. Very good lesson. Also added the use of the math functions math.sin and math.cos in python (import math) to get a orbiting Orb. placed a small "earth" in the middle for reference. ua-cam.com/video/UOPR9tsbUgA/v-deo.html

Homework done ok. 😀 Funny story. I'm using the Sunfounder Elite Explorer kit for Paul's series on the R4 Wifi. I'm ok with programming but a beginner in electronics. When it came to the LCD the one I have has a piece of electronics on the back that prevented me from plugging the LCD in to the breadboard. Should I pull it off then maybe I can plug the rest in?. Fortunately, I did some research instead and found it was an I2C module. What is I2C? So I did some more research and found how to use it and found some libraries to drive it. It works fine and is a lot better than connecting all those wires to the Arduino. So Paul, not only am I learning from you, I'm learning by doing my own research and trying things for myself. Great lectures and I can't wait for the R4 Wifi series to advance.

Hope Ant had had a sip of ice coffee too.. This video helped me a lot. spend a day testing other samples could not make it work till this lesson. Thanks.
