This version of the software has been tested as working on June 1, 2023. Reload of the project based on possible issue. Bad things will happen and you'll likely need some new parts or worse! REMEMBER!!!! NEVER have the 5V power supply AND the FTDI VCC power connected to your ESP32 at the same time. It should be wired so the circuit CLOSES when the roller is pressed (ie. This switch will initiate the sending of the 'Job Done' message to your email account. Keeping U0T and U0R connected to the FTDI adapter allows you to use the Arduino Serial Monitor for diagnostics and to get the IP Address of your ESP32 CAM Module and confirm it's running.įinally the end stop switch is wired to pin 2 on the ESP32 as shown in the diagram. ![]() IO0 DISCONNECTED from FTDI GND (It won't boot if IO0 is still connected to GND) IO0 - GND (this puts the ESP32 in programming mode)ĮSP32 FTDI (with power jumper on 5V) GND - 5V Power Supply -NEG wireĥV - 5V Power Supply +5V (disconnect FTDI VCC!) Wire up the parts as shown in the diagram. You will need a separate 5V 1A DC power adapter to run the webcam module. If you try to run the camera from the FTDI adapter, you will likely get brownout warnings in the Serial Monitor and the unit will not properly run. ![]() Your computer's USB Port will be powerful enough to upload the sketch, but it will not likely be able to provide enough current to actually RUN the module as a Webcam. The ESP32 CAM module typically uses between 80 and 180 mA to drive it. It's necessary to use an FTDI serial adapter to upload the sketch to the module. The ESP32 CAM module does not have a built in USB adapter. Then you can transfer the components to a prototype board. It's recommended you wire this project up on a breadboard to get it working. If you need to, install the ESP32 json line in your Arduino Preferences Screen and get the ESP32 Board Definitions.Īdd this line to your Arduino Preferences/Additional URLs field: ![]() This Instructable assumes you are quite familiar with using the Arduino IDE to program Arduinos and that you have previously worked with an ESP32 module. The parts were printed on a Creality Ender 3 V2 with PLA. The Flash LED on the ESP32 can be turned off/on remotely so you can check the progress of your job even if the lights are off in your workshop.įusion360 was used to design the case and ruler/switch support. ![]() I just modified the standard demo sketch provided by Espressif for the ESP32 CAM module, removing a lot of the settings to make a smaller interface that fits nicely on a phone screen. We can use the free IFTTT IoT service to send us an email when our task receives a WebHooks trigger event from the ESP32. For just $10, We get a webcam and WiFi-enabled microcontroller. I just want to see a live video of what's happening and ideally, get an email on my phone when the job is done.Įnter the humble ESP32 CAM Module. I have seen products like OctoPrint and other retail products and they're much more than I need. The idea of constantly running up and down stairs to check on a print job's progress leaves a lot to be desired. My printer is in the far end of the basement and my home office is on the 2nd floor. I just got my Ender3 V2 printer and I LOVE IT!
