As you can see in the schematic all three TC74 sensors have their SDA and SCL pins connected in series to pin A4 and A5 on the Arduino board. The two 4.7K pull-up resistors must be used when using I2C ...

This build is about using the temperature sensor in your clock. The ATMega328p, the chip at the heart of all your Arduino Uno clones, has within it a watchdog timer that clicks over at a rate of ...

Ever thought of using touch sensors on your projects but didn’t because it would be too much work? [Paul Stoffregen] proves that it can be pretty easy if you use the CapSense library for Ardu… ...

The kit brings Seeed’s Grove sensors to Arduino’s most popular board - the Arduino UNO - making the development of electronics and sensing much easier. Intended for anyone who currently uses an ...
