#SDevElectronics Sir can you please help me that when I uploaded this ir sensor code and open serial monitor automatic hex code is simultaneously displaying but I didn't press any remote button, why it is showing please help me please 🥺.
Hello there. Your video is very informative. I have a question. Is there a way to code an alert in difference of temperature change, for example, when the temperature increases or decreases within 5 degrees?
I am using a potentiometer to control and slow down the speed of the 555 and the LM4017 outputs. I'm wanting the LED's to fade when they come on and off and I am experienced with many different circuits that fade LED's. I have tried basic cap and resistor pairings at the LED's and also by using the 4017 outputs to drive bc547's transistors that turn on the LED's, again with different arrangements of caps and resistors on the base and/or emitter sides and I've also tried resistor/cap arrangements that can turn square waves triangle or sine, with and without the transistors. In all cases, I can get a very controllable fade out of the LED's but cannot get them to fade on. Is there something about the output of an LM4017 that will not allow it's waveform to change or for a capacitor to slowly charge? Or something else that I just can't figure out?
When I powered my arduino with a 9v external power supply adapter, the reading temperature every sec is not stable, it fluctuates from 32, to 19, to 22, to 27 so on.. please help
Im "planning". (I have all the parts ordered, made 3d models, preprogramed whats possible, cirquit schematics i will use to make it work with wireless energy to the top since wires cant spin and i dont want a battery, and made a programer for ATMEGA328P chips so i dont need an arduino. BTW, i will never actually assemble it)
