Breadboard Friendly I2C Temperature Sensor - TC74A0

It's rare to see breadboard friendly I2C sensors, but this TO-220 package with 5 pins is, in fact, such a thing! It's a basic temperature sensor, not the highest precision in the world, only ±2°C but it will get the job done when you need simple temperature logging or monitoring.

Pin 2 SDA2
I2C serial data. Adafruit states wiring is pin 2 is SDA.
Type · dataVoltage · 3.3V or 5V logic supported by the product page.

Light and colour

Photoresistors and color sensors both respond to light, but they expose very different signals and are not sensible drop-in substitutes.
