Source of the experiment - with a un0rick board
HP 21412A(seems like
HP 21402Awould work too). A good choice to try mechanical scanning. Simple piezo, simple motor.
Make sure that the liquid is present in the head.
- The motor (black/white pair) is driven by a DRV8834 at 5V. Setup is as follows:
- STEP: 400us period square wave.
- M1: HIGH
- !SLEEP: HIGH
- Connection to motor: A1/A2 or B1/B2
- Piezo: yellow coax
