OH!!! LOL! And so I learn I am still trying to get cables to work, nevermind wireless

I have been working on a project for a while now and I am trying to move it from Arduino over to an ESP32. I am using a A1 Lidar by slamtec and I have it working perfectly on the Arduino but I just cannot get it working on the ESP32. I am still learning a lot about both platforms and I will really a...

Can you give a bit more info on the "power level" you referring to? Is this the baud rate? I don't have enough info but I believe the voltage is more the issue here. Assuming you using the ESP32 directly you have 3.3V - The max distance on 5V is 5m with a high quality cable (using USB as reference),...

Thank you so much for this! Could I ask for help on the basic code to get this working? I cannot seem to get the PWM pin to work so the motor will spin on the Lidar. It is connected to GPIO 21 on the ESP 32

UPDATE - I placed a 104 Ceramic capacitor over the Gnd and VIN wires of the Hall Effect Switch and this is giving better results. It seems like it is more stable and I can use the switches for now. Not sure if this is the correct solution, but it's working for now.

Unfortunately not... and doing this as a hobby I admit I don't always know what I am doing. I also think it is interference... I have also tried a simple digital pin sketch that will display 0 or 1 for the Hall Effect switch, not using interrupts, just using the basic loop function and a delay(200)....

I just started using the ESP32 and having issues using interrupt pins. All of this is working on an Arduino board but I would like to switch over to the ESP32. I have 2 Hall Effect switches connected to pins 32 and 33. The Stepper motor is on pins 16 (DIR), 17 (PUL) and 4 (ENA) The Stepper motor wor...
