I am new, and this is all very messy and hard to work with, is there anyway to this all into a pcb, which I can plug into my raspberry pi, that can function as a motor driver and more like wheel encoders, and a lidar?
I used to have a hilarious toaster that was shaped like a sheep and would Baa when the toast was done. I want to recreate that without ripping apart my toaster.
In an ideal world I would like to produce a setup that could be applied to any electrical item that uses power then either switches off or uses far less when done. This way I could do the same thing for my kettle. You get the idea.
My gameplan was to use a current monitoring clamp on a small extension cord between the socket and the toaster. That way the current clamp could produce a non dangerous DC voltage that could be used to signal that the item is in use, then when the Signal drops it plays an MP3.
Can someone advise me which clamp would be suitable? I am thinking to use a raspberry pi or esp32 for the "brains" of the machine. The real question is the choice of clamp.
Thanks for reading
I built the blinking LED and it worked with the python code. Now I'm building the doorbell light from the freenove kit with a RP5. I replaced all the resistors. According to the diagram the button is the right way. I'm sure it's not a code problem because the last project worked on Thony in Python. Does anyone have any ideas?
I have recently discovered this oscilloscope online and don’t know about it .
I Appreciate everyone’s opinion 😊
This is my first project with my freenove esp32. There was definitely a learning curve going from an uno clone to using a breakout board and esp32 for the first time. Started off just learning how to use an OLED screen and snowballed in to an house plant grow monitor with high and low tracking, environment alerts/tips. Today I'll be setting up the web UI and phone alerts. Not too bad for my first legit project after learning the basics. When it's all said and done it'll be ran by 18650s just gotta transfer everything to a circuit board and figure out how to make a decent enclosure with adequate airflow.
I recently bought a kit and one of the projects was lighting up LEDs using the 74HC595 IC. I couldn't get it to work using the wiring that was provided, the LEDs didn't fully light up and some didn't light up at all. So I used the simulation in Tinkercad to just try and see what the problem could possibly be. Tinkercad simulated that the IC was being given too much current. Im a beginner in electronics, but should I need a resistor somewhere before the current hits the IC? Or is my wiring off? Any help will be greatly appreciated!
I cant figure out what's going wrong I'm staring to wonder if my button just isnt working resister is 220ohms and battery is 3.7v
Started off with just wiring up the 7 segment digit display to learn the layout of the pins turned into a sound activated 10 second count down then added an indicator LED then said screw it and added a passive buzzer and programmed a little melody to it now it counts down the notes instead of by seconds just need to adjust the sensitivity a little it's a bit to sensitive but whatever it was still a fun project and I learned a lot lol
