![]() In Visuino, at the bottom click on the "Build" Tab, make sure the correct port is selected, then click on the "Compile/Build and Upload" button. Step 7: Generate, Compile, and Upload the Arduino Code Connect " Servo1" pin to Arduino board digital pin.Connect " SubtractFromValue1" pin to " Servo1" pin.Connect " MapRange1" pin to." SubtractFromValue1" pin.Connect " HumidityThermometer1" pin to " MapRange1" pin.Connect "H umidityThermometer1" pin to Arduino board digital pin.This means that we want to display a temperature betwen 0 and 40 C. Select " MapRange1" and in the properties window set "Input Range" Max to 40 and Min to 0."Map Range Analog" component is used where we want to convert One range of values to another range of values, in Our example we get temp values from the DHT11 sensor that can be from -30 to +60 but the servo motor input value can only be betwen 0 and 1 like (0.1, 0.345, etc), so the "Map Range Analog" component will adjust this values for us. "Subtract From Analog Value" component will be used to reverse the direction of the servo rotating, so insted of rotating it from right to left we want to rotate it from left to right like a real gauge meter. If you select " HumidityThermometer1" component you can select diferent DHT type sensors in the properties window (see the picture). ![]()
