Servo movement from side to side with PWM Arduino uploaded code

You can't.

Normal servos don't provide any feedback on their position. It's not possible with software alone, unless you add long enough delay to make sure it completes the move even under load.
You either need a different servo or additional sensors.

I2C with Atmega168

Asked 2017-Sep-28 at 06:29

I'm trying to control several servos using the adafruit PWM servo controller. It uses i2c interface to communicate from the micro controller. https://www.adafruit.com/product/815

I'm using an Atmega 168 to attempt to send i2c instructions to the micro controller using a simple i2c library.

Your i2c library is wrong for the atmega168. The TWI data register is an 8bit register and you attempt to write a 16bit value into it. The issue in I2C Not working with PCA9685 uses an 8bit data TWI(i2c) driver.

The i2c is initialized properly, due to it is per default powered and clocked at the reset of the atmega168, you don't need to care. But you should better check PRR.PRTWI register, if the TWI peripheral is powered or not - maybe you use a low power library that turns the TWI off.

Furthermore, you are not explicitly ensuring for the wait time between two bytes on the bus, as you can see here: After the ACK of the Slave and the next data written on the bus, there needs to be an idle window.

So basically, you miss two major things:

8Bit data register needs to be written with 1Byte of data not with a unit16
Explicit idle time between two bytes on the bus driven by master (you)
