Morning everyone! I have a small question I want to operate 2 strips like this one with an Arduino Mega, the LEDs look a bit dim when I turn them on, like a drop in power! Should I power them with another 5 volts or should I add resistors? If resistors, how many ohms? Thank u in advance.
Adding resistors won't help, they'd just make the LEDs dimmer. a relay can be used to control power to the LED strips, maybe you need a additional power supply The issue might also lie with the LED strips themselves...

If you're powering them with arduino's 5v it won't be enough ypu could use boost converter like this to power the leds and use arduino pins only for control the relai board but don't forget the common GND
need help guys - so yst i had my hackathon in which i presented a electronic based model were i used esp32 as micro controller but asper a judge instead of a protocol which is using wifi i should use poe or powerline protocol and go with more lightweight , power efficent chip rather than esp32 which was very powerful for that task , till now i have justed build my projectsa round esp32 and arduino , So which family of chips i should look into for lightweight and custom application . I want a family in which the code remains the same for all chips but we can choose which chip with how many pins to be used . Can anyone suggest ?

Hi guys I hope you're having a good day, I want to ask you about the propellers in brushless motors, how does it effect the force, is there any suggestions for a flight that weights 400g, thank you in advance
Here's an Arduino client for MQTT: https://www.arduino.cc/reference/en/libraries/mqtt-client/ compatible with the SAMD architecture; look into it and determine your overall memory requirements. Do any of the MCUs on the platforms listed below meet your requirements?
Arduino MKR FOX 1200
Arduino MKR GSM 1400
Arduino MKR NB 1500
Arduino MKR VIDOR 4000
Arduino MKR WAN 1300 (LoRa connectivity)
Arduino MKR WAN 1310
Arduino MKR WiFi 1010
Arduino MKR ZERO (I2S bus & SD for sound, music & digital audio data)
any one has good resource for C++ for embedded As i want to learn it I can learn C++ from youtube and all but using its tools for embedded that is where i lack imagination
