Arduino ESP32 DHCP server
Arduino ESP32 DHCP server
it fixes the issue As long as you use WiFi.softAP(), you do not need to explicitly configure a DHCP server on the ESP32. It will happen automatically - the library looks after it for you.Here is a minimal example, where - in addition to setting the E

analogRead() output oscillates even though the pin is grounded
like below fixes the issue ok, analogReads normally do have a little oscillation, its normal! they are measuring voltage values and depending on the sensor you are using they will oscillate, same idea of measuring voltage using a multi meter. if you

Arduino push button problem with sending single value
Arduino push button problem with sending single value
may help you . As for the button changing from 0 to 1 too often, that is switch bounce. Google that. There are innumerable articles on something called "debounce" that will solve that issue. As for sending the signal only once per press of the button

How can I make an LED blink every n seconds without developing a lag?
How can I make an LED blink every n seconds without developing a lag?
it fixes the issue The lag is caused by the digitalWrite-calls. Your processing application waits until digitalWrite has finished and this may take 0.05 seconds or so. To fix your problem I would save the current time in milliseconds.

Advice needed for connecting multiple arduinos as slave to raspberry pi
it fixes the issue Arduino (Nano, Uno, Mega etc.) can communicate via SPI, I2C or UART. Long story short, SPI is not suitable for your application. It is used for fast data transfer over short distances (usually milimeters or centimeters), so mainly

How can I make the scope of an object created in setup() global?
like below fixes the issue It works the same way as standard C++. You can declare a pointer in the global scope and then use the new operator on other scopes to dynamically create an object anywhere you wish.

Possible to control Arduino with Node-red and Arduino sketch together?
I wish did fix the issue. Just implement a simple serial protocol. No need to combine your sketch and Firmata.If your PI's job is to visualize and provide a user interface all it needs to do is continuously receive values and send commands on demand.

How can you connect a 4 ohm 3 watt speaker to arduino mega?
I wish this help you Can you hook it up? Well technically you also could stick a fork into a power socket. Either of which is ill advised.No, you can't drive a 4 ohm speaker with an Arduino directly.
