A programmable cylinder, a system and a method change a velocity of a machine element within a compartment. A light detector within the compartment determines that the machine element is located at a first position or at a second position and/or is moving at a first velocity or at a second velocity. Switches determine that the machine element may be located at the first position or at the second position and/or is moving at the first velocity or at the second velocity. A microprocessor transmits a control signal to a transducer to alter an electrical current of the transducer to move valves of the compartment between an open position and a closed position. A compressed fluid within the interior of the compartment is changed via the valves. The machine element is accelerated and/or is decelerated to the first velocity or to the second velocity via the compressed fluid. A graphic user interface and/or a terminal accesses and controls the microprocessor and/or the transducer to move the machine element at the first velocity or at the second velocity within the compartment.
