MAX30102 heart rate sensor typically uses I2C communication protocol. The default pins for I2C are GPIO21 for SDA and GPIO22 for SCL.

I want to make a guitar hero live guitar bluetooth for play with clone hero on my phone, would this be easier buying a serial to bluetooth or should i remake the center pcb and add bluetooth interception? Also how would i have a usb cable read and write the controls if i wanted to wire mod it? Currently it requires a dongle that ive lost so my goal is just being able to use it again

Hey @Jd3n to control GPIO Pins of RPi using Node-RED with UI running on other device. You need to install ui widgets node-red-contrib-ui in node-red dashboard and use them in your node flow. I have already made a video long back to show you step by step https://youtu.be/BtNt4-v8hQw

Control GPIO Pins of Raspberry Pi4 using Node-Red

Lets learn how to control GPIO Pins of Raspberry Pi4 using Node-Red.
We'll first use raspberry pi specific node palates. And later on, we'll install ui widgets like button, gauge etc. This will let us design very sophisticated node-red dashboard to control GPIO Pins of Raspberry Pi4 from Browser.

I just read up on the Altman part quickly and found an article on the Register that said "$7 trillion is enough cash to gobble up Nvidia, TSMC, Broadcom, ASML, Samsung, AMD, Intel, Qualcomm, and every other chipmaker, designer, intellectual property holder, and equipment vendor of consequence in their entirety – and still have trillions left over”

techielew•2/18/24, 7:15 PM

So what are you buying with $7 trillion, actually?

techielew•2/18/24, 7:15 PM

The semiconductor industry?

Morning everyone ! Is it feasible to implement edge computing in a battery-powered IoT device with limited resources? What are the trade-offs and potential challenges in offloading computation to the edge?

CCamila_99$$Morning everyone ! Is it feasible to implement edge computing in a battery-power...

LMtx•2/19/24, 11:56 AM

Edge computing provides the following benefits:

Real-time local data processing enables immediate actions even without connectivity with the backend system.
Pre-processing and analyzing data before sending it to the backend system to reduce the payload size and communication frequency (resulting in lower cost and potential battery saving).
In case of connectivity issues, the device can locally store messages and transmit them once it is back online (you won't lose telemetry data during a network outage).

You might find my article interesting as it partially covers this topic.

Umesh Lokhande•2/19/24, 1:26 PM

You can use Serial UART to communicate HC-05/06 with other devices like MCU. If you want to use device as master as well as slave then go for HC-05. If only slave is good enough for your use case then HC-06 will do the job.
