Great tutorial. Thanks!

What website are you using to show wirings on breadboard? Thanks

tried to compile sketch and this is coming up Compilation error: 'Servo1write' was not declared in this scope i have tried fixing it with no luck . help please.

Very nicely presented! However, I would also like to study the code off-line. I've looked around for it, but I can not find it. Can you please post a link to it? Thanks.

Hello, I would like to build a similar circuit for a model car (mechanical transmission). It should be operated with 2 buttons (up/down). Each time you press the button, the servo should adjust by 10 degrees (or another defined number of degrees). Neutral = 0 position 1st gear = one down Neutral = on up 2nd gear = one up 3rd gear = one up 4th gear = one up The entire transmission should then be switched up (UP) and down (down) using 2 buttons. It would be great if the “UP” button also had the function if you switched it to its 0 position (neutral) for 3 seconds. I would be very grateful if you could help me with this. Thank you. Greetings Hans

How do I get to the code?

U were recommened to me by AI

thanks

deserves a subscription!!

i eally don't know where is the mistakemaking thnk why wouldn't you JUST POST THE CODE!!! #include <Servo.h> int buttonPin = 4; int button2Pin = 7; int servoPin = 3 Servo ; int ServoPosition = 0; void setup() { Servo1.attach(servoPin); Servo1.write (servoPosition); Serial. begin (9600); } void loop() { int burtonState = digitalRead(buttonPin); int button2State = digitalRead(button2Pin); if(buttonState == HIGH && servoPosition <180) { Servo1.write(ServoPositton); ServoPositton++; delay(5) } else if(button1State a == HIGH ) { Servo1.write(servoPosition); ServoPosition--; delay(5) } }

I have an issue with my circuit and im hoping you could help. I have two servos connected to a button and i want the servos to start at zero to move to 45 degrees when button is pushed (not held), and when the button is pressed again, servos move back to 0. where in my code is it incorrect ? #include <Servo.h> int buttonPin =2; int servoPin =3; int servo2Pin =5; Servo servo1; Servo servo2; int servoPosition =0; int servoIncrement =4.5; void setup() { servo1.attach(servoPin); servo2.attach(servo2Pin); servo1.write(servoPosition); servo2.write(servoPosition); } void loop() { int buttonState =digitalRead(buttonPin); if (buttonState==HIGH&&servoPosition<=45) {servoPosition +=servoIncrement; servo1.write(45); servo2.write(45); delay(10); } if (buttonState==HIGH&&servoPosition>=0) {servoPosition-=servoIncrement; servo1.write(0); servo2.write(0); delay(10); } }

Great video

how to save file with new name using push button?

thanks, have a great day

The word (Servo1) didn't activate durring writing the code broo !!

perfectly explained!

Thank you for this information. But i want to store data from the SD FILE to an array. I need a solution please help me for my project

omg thank u very much

This is exactly what I needed to control the cueing and auto lift for my new turntable build. Thank you.

Extremely good! .

Good video, but please do not add music during the explanation

Would be great if you had included bubble sort and quick sort too. Good animations and explanations anyways!

Would the light come on without a resistor?

Can you please tell me the code for when i pressed the two buttons together then the servo goes to 0 ??? i loved the tutorial from your video...keep up the good work!!!

hey hey, I used your code and it works perfect! but I want my servo to turn slower. How do you have to change this code so that the servo will turn slower, because it is going quite fast now?

Really nice video! thanks for all the information. I'm having a problem with the recording in the SD card, it only record 3 minutes of data ~10 kb in a 2 GB SD card, do you have any idea what can be wrong?

On the previous challenge I actually did the int dot and int dash. Made life so much easier when I was trying to mess with timing to get it to look right.

HAHA. Light wasn't coming on. Then I remember LED(light emitting DIODE) aka current direction limiter. I had it spun around the wrong way. Great video series. Despite my mistake I know a fair bit about electronics I'm doing this to learn Arduinos code system. I like the challenges at the end. Keep up the good work.

thank you for your turtorial, but i'm getting the error "error opening test.txt", but after it says "data written sucessfully".. after I put the SD in my laptop, and i saw 3 files (1 .sys and 2 without extention) written with strange caracters

Really loved your video. Great teaching style. I understand the coding. Have typed in code, checked and checked, but when I compile, after : else if(button2State == HIGH) && servoPosition >=0 //else if we are over 0 button 2 is on" get "expected ";" before "{" token. Can't see the error!. Frustrating

Thank you so much 👍

can you make a pdf reader with the arduino uno tft touch screen shield? i need help coz im a beginner trying to make a pdf reader thingy with a 612 page pdf file

Thank you very much 😊

were is the codes for your challenges and extension.

hi! does this work on arduino mega?

I would like to ask where would I place this code of I want to Fade Up and Down a single LED 5 times. Awaiting your replay and thank you for your informative video

could i use this to code a game.. for example DDLC? because you are able to code the game, i’m just wondering if i could code the game with this and change it more

Dude I dont know why this doesnt have more views & likes. Thank you so much! Quick tip if someone is struggling with the code using Arduino MEGA: remove GND pin from the micro SD module, and disconnect and connect the SD card. I was stuck with the "SD initialization failed" message and the latter fixed the problem. PS. you got a new subscriber. Thank you again!

Thanks for the tutorial. I subscribed

Code didn't work for me. #include <Servo.h> int buttonPin = 4; int button2Pin = 7; int servoPin = 3; Servo Servo1; int servoPosition = 0; void setup() { // put your setup code here, to run once: Servo1.attach(servopin); Servo1.write(servoPosition); } void loop() { // put your main code here, to run repeatedly: int buttonState = digitalRead(buttonPin); int button2State = digitalRead(button2Pin); Error massage says ServoPin was not declared in this scope

Well explained, thanks!

@3:26 lol oh the days before dial up, coding QBasic on the 386

EVEN BETTER... HAVE A SPDT SWITCH, AND USE THE SWITCH TO DETERMINE THE DIRECTION OF THE SERVO, AND A PUSH BUTTON, TO TELL IT TO MOVE TO THAT POSITION, WHEN COMMANDED. HOW WOULD YOU DO THAT? i HAVE TRIED SEVERAL WAYS, AND CANNOT GET IT TO STAY IN EITHER POSITION. IT JUST CYCLES BACK AND FORTH, NEVER STOPS... I AM FRUSTRATED. I LEARN BETTER WHEN SHOWN HOW TO DO SOMETHING, AND THEN I CAN APPLY IT, TO OTHER SITUATIONS THAT I AM WORKING WITH AT A LATER DATE. THANKS AGAIN!!!

OK, i HAVE BEEN ABLE TO DO THIS, HOWEVER, WHAT IF i WANT TO HOLD THE SERVO, IN EACH POSITION? SAY, i PUSH THE LEFT BUTTON, AND, THE SERVO MOVES TO 60 DEGREES, STOPS, AND HOLDS POSITION, UNTIL COMMANDED TO MOVE, BY THE RIGHT BUTTON? SAME THING WITH THE RIGHT BUTTON. I WANT IT TO MOVE TO 160 DEGREES POSITION, STOP AND HOLD THERE, UNTIL COMMANDED TO MOVE. HOW WOULD YOU CODE THAT? THANKS!!!

Conor , I would like to use a PCA9865 , have you any videos on how this would work rather than a direct feed form ardiuno board ...i want to move the servo to preset positions depending on a feed from a toggle switch ..

can you do this but instead of a display a fan, so if the temp is high it turs on, if its low, it stays of?

i understand the 'for loop' and i understand 'the 'while loop'. however, they seem to do the same thing, but are just coded differently , is that correct or have I completely missed something? perhaps each of these loops are more suitable for different situations?

hello can anyone tell me what code to use to break a while loops loop for example if i press PB 1 the code inside the while loop will run but if i press PB2 the code will stop kinda like a reset button and if I press PB again the loop will play once more

This was so fun! The extension took about 30 minutes to figure out. Thanks for the great tutorial and challenge.
