I´ve also a joystick, 4 photo resistors, the compass module HMC5883L as well as one interrupt push button and an LED on the prototype board included. I also use a second DC Motor Controller (IBT2) for a linear actuator but this one gives me no trouble. The overall project is getting more and more complex since I´m adding more and more functionality and sensors.Īrduino MEGA 2560 With WiFi Built-in - ESP8266 : 10 Steps - Instructables I do have a question about the controller sketch that uses the Adafruit PWM Servo Library.I don´t have a schematic available but it is pretty straight forward on the DC-Motors. I really want to thank Bill for the great lessons on robotic arms, servos and the PCA9685. The PCA9685 has it's own separate toggle switched power. This approach really simplifies the wiring (thank you I2C) and allows the control console to be a comfortable distance from the robotic arm. The Arduino 5v pin, ground pin, analog pin 4, analog pin 5 terminals connect to a length of common telephone 4 conductor flexible cable that runs out the back of the console to 4 connections on a PCA9685 mounted close to or even on the robotic arm. Also, the 5v supply and ground connect to the 6 pots running in parallel. I use the mini USB connector on the Nano to receive power from the console power switch. Inside the console is an Arduino Nano mounted in a screw terminal breakout shield that receives the 6 voltage divider analog inputs. The front vertical surface below the slope has a toggle switch for Arduino VCC and a LED panel light. I built a sloping front enclosure for the console which has 6 potentiometers with large (1.25") knobs. Previously, i use this PWM setting for my Arduino Board that based on ATMEga 328p microcontroller. The IO pin has a specific drive strength which will provide limited current into a load. What shape the actual signal is, though, is very much dependant on the load on the IO pin. I'm in the process of building a controller for a 6DOF SainSmart robotic arm and other multi-channel servo projects. Hi Everyone, i want to ask about PWM setting on Arduino Mega 2560. The maximum fundamental frequency you can generate is fcpu/2 - or 8MHz with the default 16MHz resonator / crystal.
