hab mir grad deinen screenshot angeschaut. Die serveradresse ohne http davor. Nur der name oder die IP Adresse. Zum Publizieren brauchst du normalerweise keinen User. Wenn User dann auch passwort. Da solltest du in die Settings des Brockers reinschauen.

Nice post. I was checking constantly this blog and I’m impressed! Very useful information particularly the last part. I care for such information lot. I was seeking this particular information a very long time. Thank you and best of luck.Best Solar Chargers To Buy In 2019

The speaker should produce constant noise if P2 is set to 0 Ω because of the voltage noise produce by the microphone and input amplifier chain. There's  no hysteresis then. If this is not the case I suspect something is wrong with the circuit. But also try different modes.

Good day to you Anto, just wanted to say thank you so very much for making this project open source and for the time taken to propely document it and have it available most importantly with the code and schematic ! You are AWESOME ! 1 Quick question, can i use a really tiny OLED that has only just started production these days, its really small, 70x40:,searchweb201602_6_10065_10130_10068_10547_319_317_10548_10696_10192_10190_453_10084_454_10083_10618_10307_10820_10301_10821_10303_537_536_10059_10884_10887_321_322_10103,searchweb201603_52,ppcSwitch_0&algo_expid=2bf5646c-c2e5-4397-963c-8223f95d1880-0&algo_pvid=2bf5646c-c2e5-4397-963c-8223f95d1880 Sorry for the long link, i dont know how to shorten these lol What would i need to change in the code, could you kindly help supply the code to help display just the voltage and current in the most simplest way because the OLED is so small, only limited data will be displayed This is because im wanting to make this into an existing tool i made, really simple MT3608 adjustable DC to DC step up converter and i wanted this project to display the output voltage and current. the same i wanted to incorporate this into a few other DC to DC converter projects, all only upto 5amps, probably wont get any higher and maybe upto 30 volts max for the voltage reading. Would you be able to help please please ? the reason why i need this tiny OLED is because i will make a homebrew PCB for it and space is severely LIMITED :( No rush at all, please take your time, id be extremely grateful for the help PS i use cadsoft Eagle for my homebrew PCB's Thanks loads in advance, you are my HERO !!!!
