We use here the breakout board from Adafruit. The board includes 10K pull-up on SDA and SCL. Pull Ups. Having pull-up resistors in place on the I2C data (SDA) and clock ... Arduino Pin SCL: yellow: ...

Check if the VCC and the ground of the sensor is connected to VCC and ground of the Arduino. Check if the SCL is connected to A5 pin and SDA is connected to the SDA pin on the Arduino Board. Check ...

the "pull up" resistors connect the SCL and SDA pins to the +3.3V pin on your arduino; they will ensure that the SDA and SCL wires stay at HIGH ... a 10uF capacitor between GND and 3.3V will also help ...

⇥ How can two Arduino boards be connected via serial communication? Connecting their SDA (data) and SCL (clock) lines, two Arduino Uno boards can be connected in the context of I²C, a type of see rial ...

It can be very helpful when you want to measure the outside, inside or other temperatures in the same time but you don’t want to use a lot of pins of your Arduino board. I2C protocol makes it easier ...

Solder-jumpers to disconnect Micro-controller SDA/SCL pins from pull-up resistors; Solder-jumper to disconnect Raspberry Pi GPIO13 from LED; Power Supply – 6.5 to 12V power supply (6.5 to 9V ...

The Arduino Uno Rev3 is the third revision of the classic Arduino Uno board. Compared to its earlier iterations, ... a more robust circuit for resetting the board, and additional SDA and SCL pins.
