An RFID attendance tracker for (medical) conferences. This replaces the sign-in sheets which makes it possible to credit the attendees their participation points without needing to touch stuff post-COVID. It's an ESP32 + TFT + RFID + RTC, which communicates with an API. The RFID cards are part of the name badges. 2.You get only extra problems because both are frameworks on top of ESP-IDF. Plus, you'll be really slow to get to understanding esp32's native API and build process because you'd do it only when you face some very pesky problems. Doing any serious ESP32 work without understanding decently esp-idf is bad idea.A Phone You Can Own. Modern smartphones are more and more a tool we don't own, but instead one we're only allowed to carry around. One that serves the interests of various tracking networks, corporate boards, and government organizations. You don't own it, it owns you. It tracks you, serves you ads, and sucks away your time with mindless ...

I have very reliable custom ESP32 boards with low ESR electrolytic bulk decoupling caps 2-3 cm from the ESP32 module. (There are smaller 0.1uF X7R ceramics close to the power pin.) My research led me to believe the placement of the bulk cap is much less critical. There are practical demonstrations of this online. \$\endgroup\$ –And I think the 8266 is better for the scope of wifi hacking. While the esp32 is also really great with all its bells and whistles. For me, I encountered many issues along the way setting up and using the 32 while the 8266 was seamless. I don't know If it was just an issue on my side. But in the end I just prefer using the 8266 over the 32. Don't do that comparison. Rpi Zero costs $15 to buy in large quantity. You can only buy one or two Rpi Zero at $5. The shop won't let you buy more after that. For ESP, you can buy as many as you need, and even at even cheaper price than retail. Other than that, Rpi Zero consumes 5W and ESP 1W while active and 50 microwatt in deep sleep. 8.ESP32 is more of a curiosity, and few employers will expect you to know it. So, in my opinion, don't stop studying STM32. It's valuable if you're looking for a job. But, keep working on ESP32, as well. I say this because it's important to know some form of RTOS, and ESP32 basically forces you to use RTOS to make anything work right.Because site’s default privacy settings expose a lot of your data.

You sound like a hobbyist without much knowledge of how much more there is to a commercial solution vs a prototype you can build at home. Odd that the esp32-c6 is available but the c5 is not.

Make esp32 based noise sensors that communicate over ESP-NOW that send messages to an esp that's connected to RPi over serial. Have RPi act as a server and you can do some data processing and visualization. ESP-NOW is a low power, long range protocol. With an external antenna, you could get a mile of line of sight range. Also the ESP32 can sleep at 2.5uA, while the Pi doesn't have a sleep mode. If you need to work with analogue voltages or minimize power usage the ESP32 is a clear winner. while the pi will be a little bit easier to work with (e.g. python in a desktop vs arduino IDE) Actually I find the Pi a lot harder to work with because of the Linux environment.The ESP32 is constantly monitoring 4 soil sensors.

nc pick 3 tic tac toe Most interesting applications for the ESP32 devkit use additional hardware -- sensors, lights, switches, etc. For example I use one to drive a series of WS2812B addressable RGB LEDs ( neopixels ), currently displays status from home automation (motion, door locks, etc). Oh yeah this is a good idea. Maybe I can buy a little co2 sensor and wire ... Add the phone number +34 644 51 95 23 to your Phone Contacts.

My opinion is that if you are in an application where you have to actually worry about supply chain attacks, you should probably not be using an ESP32. But then you can probably afford a more expensive uC solution. It's possible to audit the ESP32 application to see that it's not phoning home to a C&C server ... outdoor patio fan lowesku med school acceptance ratesara eisen measurements You get only extra problems because both are frameworks on top of ESP-IDF.
