Hello,
I am fairly new to electronics and I needed some advice with a project I am working on.
The image above is the wiring diagram of the setup. The 9V battery is not correct, instead the power supply is a Triad switching mode power supply that outputs 24V. The resistors are 10000 ohms if...
Fun project needing some support in how to get started.
This is ready for lift off over. . . Requesting advise before lifetoff to ensure it can be done and confident enough to knock this out.
*Pssh* “Uhh ya Captain speaking, strap in and get ready for a garage built, over engines are hot“...
For my next and last school year at a technological high school, an independent project with a microcontroller is the order of the day. Every student has to create an electronic project with a microcontroller. But can also have mechanical, chemical elements or the like. A few examples in recent...

I'm trying to make an IoT based project that works on Real-Time data accumulation, for that, I need to know whether the STMF0 series controller are efficient or not.
Hello, I would like to build a battery powered arduino gps speedometer.
In this arduino based project I would like to include a few features.
-I would like it to turn on some lights when It detects that the speed is going down (if the speedometer is going at 10km per hour and slowing down I...
Hey all,
I am wondering if someone could assist me in a project I'm trying to do. I feel out of place because electronics are not my forte, I haven't really worked on them so this would be my first project. In other words I need help and in the words of Michael Scott from the office you'll...
Hello,
I have to make a control system that mantains constant speed of a small car prototype using a DC gearmotor regardless of external disturbances such as slopes (small slopes).
For the development of this project I thought that a posible solution could be a control system consisting of a...
Hello,
I have been searching the Internet for days now, hours wasted scrolling through alibaba and aliexpress with very little luck.
I am looking for a 1 to 2.6 inch color lcd (doesn't matter if oled or tft or whatever) with a resolution of around 480x800 or similar with an aspect ratio of...
Our professor made us do an electronic digital roulette like the ones you play in the casino. He said we need to create something that is exactly like it, like having an output random number from 0 to 36. In addition to that 0 to 36 output, the numbers on a roulette wheel is either black or red...

MAKERbuino is a retro gaming device you can build yourself. It's purpose is to...
Dear readers,
i'm a high school Science teacher in Belgium and i've entered my students in a Science and Technology fair.
They have a good idea but my knowledge about electronics has its limits...
I've got 2 general questions first:
1) i've started with Arduino projects but do you guys know...
First off I'm totally new to the electrical scene and only know what I've learned online and hands on. Which can be a bad thing if your listening to the wrong person. So here it is :
My Problem : I am using an 18 volt dc lithium drill battery to power led lights and a car horn on a project. The...
Hello guys,
I'm studying physics, but I have a project in my extra subject and I'm really in a hurry. My electronics knowledge is really basic and I'm stuck. So any help/ideas/discussion is very very appreciated. I have to make a project with at least 2 traffic lights (I don't really know...
I know that there is plenty of stuff on the internet titled: Electronics Projects for Beginners. But I´m looking for a different advice, and for that, I think I need to ask directly professional and more skilled folks that I hopefully will find in here.
I'm very interested in electronics but I...
