Servo tester & monitor
For :
- testing servos
- finding min/max signals to suit a specific installation
- monitoring servo signals in a running installation (and enforcing min/max)
- monitoring servo voltage & current
Runs on a Wemos D1 Mini Pro 1.1
Uses the fabulous ArduinoMenu from https://github.com/neu-rah/ArduinoMenu (but you can get it via the LibraryManager) and ClickEncoder from https://github.com/0xPIT/encoder/tree/arduino
Hardware:
- Wemos OLED shield: https://wiki.wemos.cc/products:d1_mini_shields:oled_shield
- Generic click-encoder for UI
- Adafruit INA219 high-side current & voltage monitor: https://www.adafruit.com/product/904
- Polulu 5V step-up step-down regulator to provide logic power from servo power
