Software Setup NOTE: Before we can use the code, we must first download the libraries Therefore, Wire.h library when used, utilizes A4 and A5 for the SDA and SCL pins, respectively. A4 and A5 pins can't be utilized for analog inputs since the SDA and SCL for I2C share the same pins. Highlighted with the red arrow and circle above, Robotdyn UNO has two extra analog pins that we utilized on top of the standard 6 analog pins. The Robodyn UNO also requires power for the chip to function.

The servo shield requires an external power source as indicated in the schematic to power the servo motors (with 5V 2A DC power, we can connect 1-6 motors without experiencing power issues). Note that the PWM Servo Shield goes on top of the Robotdyn UNO. Any digital input pin on the Arduino can be used to connect the pushbutton output. If the cap is held down long enough to produce an audible click, a push button switch output is also available. This module has two 5K potentiometers that are spring-loaded and have X and Y analog outputs that may be connected to analog inputs on the Arduino. If just one terminal, the wiper, is utilized, the potentiometer functions as a variable resistor. The motor rotates from 0 to 180 degrees depending on the duty cycle of the PWM signal given to its signal pin, just like other RC servos.Ī potentiometer, also known as a variable resistor or rheostat, is a three-terminal resistor with a sliding or revolving contact that creates a changeable voltage divider. It has a stable constant torque range and excellent holding power.Ī metal gear servo motor with a maximum stall torque of 11 kg/cm is the MG996R. The twin shock-proof ball-bearing MG995 servo design has a metal gear, making industrial production quite doable. It is a reasonably priced, low-power motor.

MG995 High Torque Servo Motor Metal Gear (360 rotation)Ī robust, dependable servo motor is the MG995 servo motor.

The output shaft can only rotate 180 degrees because it is fastened to the potentiometer.Ī small DC motor, plastic gears to boost torque, a potentiometer to indicate the output shaft's present position, and a control circuit make up the SG90 Servo Motor. Without solder jumpers, the default address is 0x40.Īn actuator that delivers a rotating motion roughly between 0° and 180° is the SG90 Servo Motor. This shield's solder pads allow you to choose among 62 addresses (0x40-0x7E). This I2C device (which makes use of the Wire library) can typically be shared or stacked with other I2C shields and devices (including numerous PWM/Servo Shields), so long as they all have distinct addresses. All 16 channels will be driven simultaneously by the on-board PWM controller without the need for further Arduino processing. With just 2 pins, this16-Channel 12-bit PWM/Servo Driver Shield can drive up to 16 servos over I2C.
