This kit turns your TEC1-12706 Peltier module (not included) into a measurable power source. Connect the Arduino Uno, INA219 sensor, OLED display, and two DS18B20 temperature probes, and watch real-time voltage, current, and power flow on the screen - while logging hot and cold side temperatures. It's a hands-on way to explore the Seebeck effect without any prior electronics experience.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eA compact bench instrument that measures the electrical output of any Seebeck-effect generator. The OLED shows live power (mW), voltage, and current drawn from the temperature difference between the two DS18B20 probes placed on opposite sides of the Peltier module. Use it to compare different heat sources, cooling methods, or module orientations. The system runs on a 9V battery, so you can take it anywhere.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Learn\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eCalibrate an INA219 high-side current sensor over I2C to measure micro-watt power from a TEG.\u003c\/li\u003e\n  \u003cli\u003eInterface dual DS18B20 digital temperature sensors with Arduino using OneWire protocol.\u003c\/li\u003e\n  \u003cli\u003eDisplay real-time sensor data on a 0.96-inch OLED using the U8g2 library.\u003c\/li\u003e\n  \u003cli\u003eUnderstand the Seebeck effect and how temperature gradients generate voltage.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eKit Contents\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eComponent\u003c\/th\u003e\n\u003cth\u003eQuantity\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eArduino Uno R3\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eINA219\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDS18B20 Probe\u003c\/td\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e0.96in OLED\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e4.7k?
