    Go to File>Preferences and increase 'Editor font size'. This should also increase font size in serial monitor.Or just mouse over on the serial monitor and press Ctrl + scroll mouse up.

    Is the LED glowing continuously when you keep the switch pressed? If not, there is some problem.Because, from what I can see in the video, the LED is blinking at an interval of every 1 second. Is there any error when you upload the code to your board. Because it seems that your board is running the default 'Blink program' that it came with and your program didn't get uploaded to the board.

    Hey,The Uno board is capable of having only one program at a time. Whenever you upload any program on the board, the previous program gets overwritten. So since the default Blink program is running on your board, I guess the Morse code program is not getting uploaded.When you upload a program using the compiler, you should get an error if the code if doesn't get uploaded. There can be multiple reasons for this (eg. wrong board selected in the compiler, Arduino drivers are not installed correctly on your PC, communication IC may be damaged on the board, etc.)I think since you are new to this, go through some youtube videos for basic Arduino Uno programming. It will help and you should be able to do the project very easily after that.Do try again. If you are still facing problem, message me…

    The circuit seems fine. Can't say what the problem could be?When you press the tactile switch, does anything show up on the serial monitor on your PC?To troubleshoot, you can try one thing. Instead of using the external LED use the built in LED on your board. Don't change anything in the circuit. Only change the LED pin number in the code. Pin no. 13 is connected to the LED on your board with an 'L' printed near it.So instead of "int ledPin = 4;", write "int ledPin = 13;" Rest of the program remains the same.Now check if pressing the tactile switch lights up the onboard LED labelled L.

    Hey there,1. Can't pinpoint what the problem is. When you press the reset button all I/Os are triggered so the LED must be lighting because of that. There must be some issue with either the circuit, the code or in worse case the board. If possible, upload a pic of the circuit. I will be able to help you better with that. Also did you directly download and use the file 'Morse_code_decoder.ino' or did you type the code manually in your compiler.2. Using an Elegoo Uno R3 should be fine as Arduino is opens source. The technical specs of both the Elegoo board and the Arduino board will be same, the only difference being it is manufactured by different companies. Also, I used a generic board from China, which didn't even have the manufacturer's name.3. All the three circuits are the same. They …

The first one is a circuit sketch, second one is a circuit diagram and the third one is an actual photograph.Try checking the connections and code again. If it is still not working, upload with pic and I'll help you troubleshoot further.

    Using a microphone might need different amount of time than a push button. Try changing the 600 millisec time used for signal length and try out different values.

    Yes, you can use this code on Adafruit Circuit Playground Classic.I have never coded a Circuit Playground myself, but I feel the code should work fine. The only things you might have to change is codes relating to the input push button and output LED and directly make use of the onboard LEDs and buttons.Do try out and post your results on the website.

    Not quite sure why that would happen.What output is it showing on the serial monitor?

    Hey, I haven't really worked with piezo speakers myself. But it is simple enough. Try the link below.https://www.instructables.com/How-to-use-a-Buzzer-Arduino-Tutorial/

    Hi. No I didn't really do any calculation for this. The only purpose of the resistor is to limit the current flow through the circuit. Without the resistor, the Arduino may get damaged over long period of usage. As for selection of 220 ohms, it's just a thumb rule that I follow. You can use a higher or lower resistance resistor - it will only affect the current flowing through the circuit, thereby changing the intensity of the LED. If you are still not satisfied and want to learn more about it, go through the following two articles - they explain it very nicely.https://hardwarefun.com/tutorials/calculating-corr...https://www.evilmadscientist.com/2012/resistors-fo...

    Whoa!!! That is some real complex wiring there. Awesome work. Do post some videos.

    Hey, nice idea using touch sensor. I think you'll be able to operate it more smoothly with a touch sensor instead of a push button. However, you'll have to do slight modifications to the code.I used the internal pullup resistor along with the push button to simplify the circuit. So when the button is pressed I used to get a low signal and when it was released I used do get a high signal. In your case you'll have to change the code as the touch sensor will directly give a high signal when pressed and vice versa.Do post and share your project after building it.

    Hey, I am not sure what this error is related to. Did you type in the code manually or did you directly download the .ino file and try to upload it.?

    Using an LCD should be simple enough. Instead of using Serial.print, use a standard LCD library with print or write command. For the buzzer, the code should be similar to the one I have used, only, instead of the LED diode connect a buzzer.Hope that helped. If you need help with something specific, do ask.

  • Awesome. I am definetly going to try this. But I was thinking of upgrading it a bit. Perhaps add a label that shows the Cartesian co-ordinates of the current position of the gripper. And also providing a linear jogging mode in addition to axis jogging that you have shown.

    Awesome idea. I have never really worked with a thermal printer but I guess you should check out the one by Adafruit. It's quite neat ans simple. As for your idea of using a transceiver, I am working on something similar right now. I am using an HC-05 bluetooth module to send data to my Android phone. But, your idea with with transceivers sounds cool too. Do keep me posted of your progress.
