Re: Unpredictable PWM behaviour when powered via 5v pin
I cannot say if that is the problem. I can say you should never use a regulator without a bypass cap on it.

Re: Unpredictable PWM behaviour when powered via 5v pin
Does your LM7805 regulator have 0.1uf bypass caps on both the input and output ?

Re: ESP32 on development board would not accept Flashing when sent on TX Rx pins in spite of Grounding IO0
Dam, something so obvious... Good call ESP_Sprite!I think that it's more likely that the issue is that your devboard already has an USB-to-serial-converter connected to the Tx and Rx pins, and that connection is interfering. Suggest you use the onboard USB port to program the board instead.

Re: ESP32 on development board would not accept Flashing when sent on TX Rx pins in spite of Grounding IO0
If you want to automatically flash you will need 2 more connections. EN & GPIO0. Your USB to serial board does not support it. There is a sequence with these 2 pins to put it into flashing mode. You can manually put it into flashing mode, but you will have to press and hold down the boot button, the...

Re: ESP32 wrover dev board with 16MB flash/8MB PSRAM?
This place has the 16MB, but not with 8MBram, just 4MB.

Re: What would you like to see in The Next Chip?
A ESP32 module with onboard Ethernet PHY chip. Without the 9 RMII lines internally connected there will be 10+ lines left only to be routed outside to make the end-users' RJ45 application much easier! Na, that will increase the cost for all who dont even use Ethernet. Adding a PHY chip is ultra sim...

ESP32-S2 With LCD interface, Confused
I was looking into the new ESP32-S2, primary because it says this: With LCD interface and 14 configurable capacitive touch GPIOs, ESP32-S2 provides the optimal HMI solution for touchscreen and touchpad-based devices. From this Link: https://www.espressif.com/en/products/socs/esp32-s2 I was looking a...

Re: ESP32: Use Arduino or ESP-IDF?
In short, I can't express how frustrated I am with Arduino, and how great ESP-IDF has been. Simular issues here. I started out with Arduino only because I was new to espressif. As time moved on and I started moving on from simple hello world, toggling GPIO and so on to adding peripherals and making...

Re: ESP32 DEVKIT and 12V NPN Sensor
Try sticking a delay(10); or delay(100); in your loop().

Re: ESP32 DEVKIT and 12V NPN Sensor
What voltage is sensors output ?
If it's 5v you have a problem. You need to get it to 3.3v.
