Resistor generator

Customer's demand:

• The factory needs an accurate resistor generator that can be adjusted in many different ranges to test the measuring device at the factory.

Solutions:

• Use the controller kit developed by Indruino to program the controller, whose core is an ATmega328p chip.
• Use the 4.3-inch samkoon screen to design an interface for the user to set the resistor value that they want to create.

Result:

• The correct resistor with an error of +/- 0.02 ohm was given.
• Put into use at the factory to test the resistance measuring devices at the factory.
