Addressable LED Strip Odd Colors with Arduino | Weird Behavior
I was trying to run some test code using a strip of addressable LEDs and my Arduino, but every time I ran the program, I got odd colors and the last LED color was green. Sometimes

Lolin32 Lite Notes
These are on-going notes I have for the Lolin32 Lite board. Specs and graphic: https://mischianti.org/esp32-wemos-lolin32-lite-high-resolution-pinout-and-specs/ Flashing the Board
Connecting to and Controlling an Optidrive E3 VFD using Arduino and Modbus RTU
Note: For those interested in virtual production, I have published a version of this on this website as part of a collection of virtual production resources. While working on build
Digispark ATtiny85 AVR USB Connect/Disconnect - Programming the Dev Board
I bought a couple little ATtiny85 development boards a while ago and I've used them in little projects here and there, like creating a 3D printed stoplight with my son. It's a grea
Driving a Max98357 with an ESP32C3 single processor arduino
Max98357 For part of a hobby project, I wanted to replace a piezo buzzer with a speaker. I have heard Arduino can drive speakers directly with PWM (never done it myself), but inste
PIO Adding a New Board for Lolin ESP32-C3 Pico
There is a sense that things are right in the world when things are just like they should be. One such instance is declaring an Arduino board that has not been done so yet. Fortuna
Lolin esp32-c3 pico Notes (PIO, Qwiic Stemma QT)
I don't work on this often, so when I do, I feel like I'm having to go back and figure things out. These notes will hopefully save me some time. Drivers The chip on these dev board
ESP8266 PWM LED Control - AnalogWrite 255 Low Output
Problem: While working on a project to create light panels rendering LED values via DMX over ARTNET, I found that the LEDs would only ever get so bright, falling quite short of the
Non-blocking Arduino/OLED SSD1306 Animation Manager
Problem: I'm working on a project that involves a bit of screen usage and I need to organize things in a way that they will work without blocking my event loop. (I plan to share th
Addressable LED Strip Flickers with Arduino | Weird Behavior
Problem: While working with Arduino and addressable LED strips (a few times now), I tend to wire up everything (with external power since the LEDs can draw a lot of current) and go
ESP8266 FastLED Pin Assignment Confusion
Problem : While trying to use an ESP8266 D1 mini Arduino board to control some addressable WS8211 LEDs, I found that it didn't seem to work. Solution : After some reading, I found
Arduino Pro Micro (Atmega32U4) - Can't Upload Sketch - Board Bricked
Problem: I recently purchased some pro micro clone boards with HID support. I was able to upload to the first board without a problem, but then I was unable to upload to the same b
