50K Variable Resistor. Wattage of the resistor can be simply gotten by multiplying the variants ie 07 x 1 = 07 watts or simply 1 watt The calculated resistor ensures that the output current to the LED never crosses the 1 amp mark thereby safeguarding the LED from damage other values for the remaining resistors may be appropriately calculated for getting the desired variable current.
This flex sensor is a variable resistor like no other The resistance of the flex sensor increases as the body of the component bends Sensors like these were used in the Nintendo Power Glove They can also be used as door sensors robot whisker sensors or a primary component in creating sentient stuffed animals!

Digital Resistor If you want to put a microcontroller into the mix there are plenty of digital resistors that could be used as a variable resistor the microchip MCP41XXX series (256taps) DS1804 series (100 taps) The side effect of this solution is that digital resistors have a big tolerance (±20%) and could be not the most accurate device if you want to set a specific delay.

030V 05A variable supply with current adjustable This circuit is better than the above circuit Because use CA3140 for Control Current and Voltage output in easily And full overload protection P150K for control current R2050K for Adjustable output voltage R195K for fine Adjustable voltage output Transformer—use 58A at 32V and 18V.
In the circuit the slider of the 50K potentiometer is connected to analog input pin A0 of the arduino The LED is connected at digital pin 12 of the arduino R1 is a current limiting resistor The working of the program is very simple Arduino reads the voltage at the analog input pin A0 (slider of the POT) Necessary calculations are done using this reading and the duty.

PWM stands for Pulse Width Modulation and is the method to produce variable voltages using digital means Typically variable voltages come from analog circuits and digital circuits produce only two voltages the high (5v 33v 18v etc) or low (0v) So how it is possible that digital circuits can produce avoltage that is between the high and the low voltages? If you bring a.
