Current + voltage sensor INA219 with TinkerPie
Measure how much power a motor or solar panel uses.
| Type | Smart sensors (I2C) |
|---|---|
| Connect to | SENSOR port · 0x40 |
| Gives | V and mA |
| Simulator | Yes: a control appears under the simulated board |
How to wire it
Plug into any SENSOR 1-4 port (SDA, SCL, 3.3 V, GND). Each type has a fixed I2C address, so different types can share the bus.
Code
In blocks: Accessories category in TinkerPie Studio. As code:
// JavaScript
