I am doing a car parking system for a school project using the ESP8266. I have the entrance working initially, but upon adding the exit into the code, it seems that the whole code stopped working. I wanted the Serial display to show "4/4 parking lots are left", but after adding the exit servo into ..

The project I am carrying out is made up of an ESP8266, a TMP256 (Temperature detector) and a Web Service. What I have to give is: take the data that the sensor returns to me and send it via GET method to an API. This is my script: #include <ESP8266WiFi.h> const char* ssid = "xxxxxxxxx"; ..
I am working with an OLED display connected to Arduino nano, and I have created multiple classes for my other components. But for the case of display, I need to create an object Adafruit_SSD1306 display(OLED_WIDTH, OLED_HEIGHT); and then call begin method using the display object display.begin(SSD1306_SWITCHCAPVCC, OLED_ADDR); and I need the display object to be ..

I can’t upload my code to my uno. I already restart my board, update the module, reinstall the IDE and there is no input on the Tx/Rx pins. I try to upload an empty file that only have void loop and void setup also failed. An error occurred while uploading the sketch C:UsersHPAppDataLocalArduino15packagesarduinotoolsavrdude.3.0-arduino17/bin/avrdude -CC:UsersHPAppDataLocalArduino15packagesarduinotoolsavrdude.3.0-arduino17/etc/avrdude.conf -v ..
Basically, i am writing a Arduino Code. I have a pre defined built in function which returns a certain value. It is a void function without any parameters being passed to it Somewhat like this void print() { print(a); print(b); print(c); } Is it possible for me to get those values for a,b and c? ..
i want to calculate the "char*" and give back the result as a "double" (or "float"). char* calculation = "2+2*2"; double result = atof(calculation); double result: 2.00 The problem is that it just doesn’t calculate automatically and just stops scanning the "char*" at the "+". Any ideas? And NO I don’t want to declare "calculation" ..
I am using arduino IDE. I have an SD logger program writing x and y coords to one file on SD. The x/y point pair is converted from GPS Decimal Degrees, and the saved x/y pair is per line with line data separated by a comma. X is always the first number set, then comma, ..
