There are legitimate downsides to the ESP32 not mentioned. It's terribly inaccurate for analog read (especially when WiFi/Bluetooth is running), draws 3-10 times the power than other modern microcontrollers, its PWM is software emulated so it's unusable if you need precise and accurate PWM. Just some things to be careful about because some of these are dealbreakers for some projects.

It depends on application. I'm a hobbyist, so I never use the same microcontroller for every project. When I only need to read and send data (e.g. via 433mhz network), attiny85 is irreplaceable, consumes little and does everything necessary. If you need to run the display and do other things at the same time, and the RPi is too big, then the esp32 is the best option, but as someone below said, analog reading is bad, consumption is huge, etc. it has its downsides... (many people, including me, never use its low power core, because it is complicated to program)

People obsess over the esp32 clock speeds, when was the last time you maxed out your arduinos clock speed? I build engine management systems with arduino and still have not maxed it out yet. Arduino is older technology, it's now expensive and and there are newer, more advanced controllers to move on to. I wouldn't even consider starting with arduino now, start with raspberry pi pico or esp32. Arduino has almost disappeared here in Japan, it's the 3.3V logic when your old designs use 5v that is the annoying bit.

Be aware that the ESP32 uses some proprietary Code (Espressive keeps this secret) for its WIFI capabilities. Nobody - except Espressive - knows exactly what this does. Keep in mind that the ESP is a Chinese product. And if I‘d keen to know what others do then I‘d do my very best to keep control over THIS core component of a system! So I‘d NEVER suggest to use an ESP32 in an environment where Security/ the protection of Data is an subject! But interestingly this is no issue. But these Folks are also very calmed by using the Windows Cloud… 🙄

An Arduino is wonderful for remote sensor applications that either don't need a data connection or are able to connect in other ways. They're great for repetitive tasks that don't require much processing overhead. ESP32 is enough to run an entire mac classic emulator with CPU to spare. It's overkill for many applications. It's nice, though, if you need the power, or just don't care about power utilization or code optimization.

Well that and also arduinos are a lot more accurate on the analogue read and pwm signals which can matter a ton depending on what you're doing, For example, if you're trying to read the tachometer output from your standard 12 volt PC fan and then control that fan with PWM an ESP is Just too inaccurate. where as an Arduino will always give you a correct signal. tested this myself using a board that came with an esp32 and Arduino mega chip in the same board and I found that when measuring the same tach signal The ESP jumped around a lot more and was just not as accurate whereas the Arduino gave an accurate value every single time

@fortheregm1249 9 күн бұрын

@@AstoundingAmelia Well i will also say that there are alot more things you need to be aware of when coding an ESP compared to Arduino. very often requiring the same functionality I've had to spend considerable time researching on how to get it done right. i.e for analog input accuracy you are comparing 10-bit to 12-bit, so ESP is 4 times more "accurate". But the value it outputs is not linear so you need a very complicated math equation in the code to actually get the more accurate results. So ease of use is defo a pro for arduino. Mega 2560 is an absolute BEAST btw, but then you are comparing an ESP to a chip that costs 10X - 50 X its price .

@fortheregm1249 9 күн бұрын

@@AstoundingAmelia maybe I'll also add that for ESP input you are on a lower logic level with higher impendence and sensitivity so you are much more susceptible to noise, likely needing a small cap and resistor to read the results right on analog input. So the ease of use also extends to hardware design. its just a more advanced chip with more hoops to jump, TBH the chips I always end up using is the pro mini unless i need wifi.
