I'm running a Python sketch in Windows which communicates with an Arduino sketch on a Nano Every. Both sides constantly listen for input from each other via the serial port, run by purejavacomm in Python. Each side sends a heartbeat so that the other side knows the communication is still working.
Normally, Python correctly sees the "HI" heartbeat (0x48, 0x49, 0x0D) sen...
I am having trouble activating the Red LED or IR LED on my ProtoCentral AFE4490 Pulse Oximeter kit. I have performed extensive troubleshooting steps but cannot get the pulse oximeter LED's to illuminate and get a clean PPG signal. ...
I have an espresso machine that gets its water from one of those 5 gallon blue water bottles (I would plumb it, but our water here is WAAAAY too hard).
If I ever accidentally let the bottle run out of water, the rotary pump in the espresso machine will be ruined, which would be a costly mistake.
I know that I can install some sort of magnetic float sensor insi...
I'm building a PID-controlled balancer using the MPU650 imu and the Adafruit libraries to control it. When I go to run my code, it gets stuck at the mpu.begin() line and repeats up to there once before just locking up and not progressing at all. I've put the relevant section of code and serial monitor output below. This only occurs when the MPU6050 is powered and connected, b...
I'm currently prototyping a device using an Arduino Nano ESP32 and a handful of BMI160 breakout boards. I am trying to get 2 I2C buses working, in order to have 4 IMU boards active at once. I'm running into a problem with the second I2C bus. I believe I have the first bus working (adapting DFRobot_BMI160 library), as it reads 1 or 2 IMUs, but when I try to get the second bus ...
