the SDA (data line) and SCL (clock line) are on the pin headers close to the AREF pin. The Arduino Due has two I2C / TWI interfaces SDA1 and SCL1 are near to the AREF pin and the additional one is on pins 20 and 21.

Choose the board, COM port, hold down the BOOT button, click upload and keep your finger on the BOOT button pressed. When the Arduino IDE starts sending the code, you can release the button and wait for the flashing process to be completed. Now, the ESP32 is flashed with the new firmw...
Due to my...ahem...unfortunate ignorance way back when I first created this project, the entire codebase (all platforms, cores, and device libraries) are all inside of this one giant repository. That means there's no easy IDE integration the way most libraries work in the Arduino world ...
Miniboot is an I2C bootloader for Arduino, tested on AtMega328p. It is designed to reflash the Mega328p with code residing in an external I2C memory or another I2C device. For testing, CAT24M01 1Mbit (128kByte) external EEPROM was used. ...
The address that you are using for I2C communication seems incorrect. The bus address used for I2C comunication on Arduino hardware is 0x48. You can also scan the I2C bus to get the I2C address. You can try the below code snippet. ...
TCS34725 I2C Color Sensor For Arduino SKU: SEN0212 Introduction The TCS34725 has a high sensitivity, wide dynamic range, and includes an IR blocking filter making it an ideal color sensing solution for use under varied lighting conditions. The sensor also includes four ultra-bright LEDs to allow...
