Thanks! Almighty Tallest? The picture below with a regular mega and an ESP-01 is an exact equivalent of what the Mega WiFi can do where I connect the mega to my laptop and the Mega talks to the ESP through Serial3. In total the microcontroller has 54 digital I/O pins and 15 are able to produce a PWM signal. Download and install that for your OS. Very helpful! One tip is that you watch the video entitled Residential Automation with Arduino Mega and ESP8266 for more details about this subject. Maybe I am missing something, but I can not seem to find a reference anywhere on this page!?!? This is not recommended because you bypass the LD1117S50CTR 5V voltage regulator and have to make sure that the voltage level is stable. We can see that they are similar, but in the 2560, we have the USB printer, which is a large connector. If you connect an antenna on this device, you will have a huge benefit, as it will increase your reach, straight from 90 meters to 240 meters away. If you need a lot of input pins the Arduino Mega has no competitors. I needed an ESP8622 board with 16 analog pins and this board seemed like the best option. there is a way to use the digital as analog but my input voltage wont match the 0-3.3v and only be 0-1v so accuracy will likely be pretty poor. For the Mega there is no build in WiFi. To record the Arduino, there is no mystery at all. "facepalm...."Right now i just wanted to program the mega part to try out a LCD first. Lave a comment below. It may void the esp8266. In the image below, we zoomed in on the key that changes the serial port of the Arduino Mega. I cant get any sketch to upload to my mega2560 + WIFI R3 board...im getting " avrdude: stk500v2_ReceiveMessage(): timeout " been at it for a few hours and im about to break it in half and get a regular mega. Compare the Mega to other Arduino and ESP8266 based microcontroller. but i do have an actual question. Where can I get the codes for this project? I would like to run the ESP8266 in AT mode, but I am completely confused about your statement to "download the PDF file" (step 5) - how does that help me run it in AT mode?Where can I get the AT mode firmware for the ESP8266 it doesn't seem to be in any of the samples. appreciate the effort to create it. So fiddling with the switches lets you program one or the other or run connected to the USB for using the serial monitor. Here, we do the same thing mentioned above, but while using the Arduino Mega with integrated ESP. The ATmega2560P comes with builtin bootloader which makes it very easy to flash the board with your code.
