Trying to establish SPI communication between two Arduinos
I'm trying to establish SPI communication between two Arduinos. When I directly wire pins 10, 11, 12, and 13 of both Arduinos, it works well and I can make them send and receive data.
For a project I'm working on, my idea is to develop a quick connection between both Arduinos, something like a plug-and-play connection, so I thought it was a good idea to use a USB-C adapter to easily connect them. I chose USB-C because it is a cheaper solution in terms of adapters and cables.
I imagine it is a bad idea since it's not working; there's no communication between the Arduinos....
Solution:
can I use this sensor like a flex sensor to detect finger bending movement?
Guys, can I use this sensor like a flex sensor to detect finger bending movement?

Hi wafa, I found this article that explains how does it work and how to collect it's signal

Troubleshooting Erratic Behavior in Solar Electricity Router for Excess PV Power Management
Hello, I need help. I'm trying to make a router for solar electricity. The goal is to direct the excess electricity produced by the PV panels to a household resistive load rather than sending it to the grid for free.
Reading the teleinfo port of the Linky meter works very well.
When I use the dimmer library in one of the example sketches, my incandescent bulb works perfectly.
But, in my router sketch, the bulb behaves erratically. I've been working on this for a month. If you could help me, thank you....
Reviewing My ATtiny85 MIDI Controller with CR2032 Battery: Schematic and Assembly Feedback Needed
Working on a tiny MIDI controller setup using an ATtiny85 chip using a CR2032 coin-cell battery. I think everything is good here on my schematic, but would be open to other opinions before I officially order it. Going to make it in three snap-off pieces, tied together with four screws, so I'm a bit nervous about that since I don't think KiCad will really check it correctly.
Also, my analog input voltage divider circuit w/ four buttons on two inputs is largely untested, though I think it should work. Haven't really examined the resistor values closely, but I believe it should be able to detect when two buttons are pressed per a middle resistance value.
Anyway, I'd welcome any thoughts, thx!...
Does the ATtinyx5 series allow for capacitive touch without a resistor?
Hackaday is having a business card contest https://hackaday.com/2024/05/07/the-2024-business-card-challenge-starts-now/and I decided to throw something together to enter. I doubt it will win, as mine is just a simple LED/battery holder. But it's been something that I've been thinking about for a while, so seems like a good excuse. Maybe it'll get one of the runner-up prizes.
All that being said, I'm fairly happy with the front, but the back could probably better. Any suggestions to help with its aesthetics and/or usefulness (whether front or back)?...
Solution:
- doesn't look like supporting capacitive touch as a peripheral. So external components will be required. Also take a look at this MCU coming with touch sense peripheral MSP430FR2512 ( design manual https://www.ti.com/lit/an/slaa842b/slaa842b.pdf)
