HI. I have just built a 6 servo robot arm which used bluetooth but it is not going to be suitable for my 6 year old Grandson. I have tried altering the sketch to allow control of pins 5-11 and the additional two inputs from a third joystick and while it compiles OK only the outputs and inputs in the original sketch work. Is there a sketch that I can use organ you point me in the right direction to get it to work on all is servos please?

Excellent concept of recording coordinates with hardware interface by joystick. Shall highly appreciate if this is extended to using 16 servos or more by connecting a I2C servo driver control board and interfacing to Arduino.

Hi .. Thank you for sharing your great project. If we want to replace the base servo motor with a stepper motor, what changes should be made to the project code? (L298 or CNC shield as a driver)

In version 1.2. was improved recording of coordinates. And some bugs was removed.

On program start the servos are set to start positions defined in software (in degrees): int startBase = 90; int startShoulder = 90; int startElbow = 90; int startGripper = 0; So you can change this values to angles you need on start of program. You can also set limitations for each servo (mimimal and maximal angle): int minBase = 0; int maxBase = 150; int minShoulder = 0; int maxShoulder = 150; int minElbow = 0; int maxElbow = 150; int minGripper = 0; int maxGripper = 150; From 0 to 180 degrees.

It is simple. Before fixing the servos make sure they all are at 90 degrees or centre position. One can use a very low cost (<$2) servo tester or fix a drum on the servo and manually turn to left right to ascertain the centre position. You may visit https://technoaids.com/servo-tester/

hello. Thanks for your great project. I have tried to add 1 servo controlled by a 3rd joystick, but the modifications i made to the code are not suitable. I posted the code in the forum so that maybe someone could get the right changes https://forum.arduino.cc/t/control-5-servos-3-joysticks-recording-coordinates-arduino-uno/1321649/4 Any idea how to control 5 servos with 3 joysticks with recording coordinates?? Thank you
