Cool. You are welcome.

Hey, I haven't really worked with piezo speakers myself. But it is simple enough. Try the link below.https://www.instructables.com/id/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.?

Awesome!!!

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.
