| + | Not having proper soldering tools leads to bad electrical contacts and makes it a nightmare to debug any issues. Thankfully, jamming a wire through the ESP32 DevBoard pins worked brilliantly, just don't ask me to move it anywhere. | ||
| Initially I wanted to use both BLE and a webpage hosted on the ESP32 itself to allow control of the LED strip from multiple sources but due to memory constraints on the ESP32 I had to choose only one (91% memory usage with the BLE implementation alone). | Initially I wanted to use both BLE and a webpage hosted on the ESP32 itself to allow control of the LED strip from multiple sources but due to memory constraints on the ESP32 I had to choose only one (91% memory usage with the BLE implementation alone). | ||
