The mode of operation setting can be changed using this function If you are using this ADC in a battery powered application, you should use Power-down single-shot mode. Mode of Operation : ADS1100 has two mode of operation, one is Continuous conversion mode and other one is Power-down single-shot mode. Gain Settings : ADS1115 supports upto 4 gain settings and these gain settings can be changed using this functionĪds.setGain(GAIN_ONE) // 1x gain (default) The ADS1100 has a number of settings, which can be configured based on user requirements.

The ADC board has 2 address jumpers, which can be used to set upto 4 different I2C addresses.ĭownload and install Arduino Software (IDE) on your machine. This ADC can be used as single or differential inputs analog to digital converter, signal channel differential analog to digital converter or single channel comparator.
ADS1100 16-Bit 1-Channel Analog to Digital ConverterĪDS1100 is a 1 Channel 16 bit resolution Analog to digital Converter. Hardware needed to interface ADS1100 16-Bit 1-Channel Analog to Digital Converter with Arduino This Sample code can be used with Arduino.

As you turn the pot, the values will change, corresponding to the voltage coming into pin A0. Now, when you open your Serial Monitor in the Arduino IDE (by clicking on the icon on the right side of the top green bar or pressing Ctrl+Shift+M), you should see a steady stream of numbers ranging from 0.0 - 5.0. You can do this with the command Serial.println() in your last line of code: To scale the numbers between 0.0 and 5.0, divide 5.0 by 1023.0 and multiply that by sensorValue :įloat voltage= sensorValue * (5.0 / 1023.0) įinally, you need to print this information to your serial window as. To change the values from 0-1023 to a range that corresponds to the voltage the pin is reading, you'll need to create another variable, a float, and do a little math. Next, in the main loop of your code, you need to establish a variable to store the resistance value (which will be between, perfect for an intdatatype) coming in from your potentiometer: In the program below, the very first thing that you do will in the setup function is to begin serial communications, at 9600 bits of data per second, between your board and your computer with the line: In between, analogRead() returns a number between that is proportional to the amount of voltage being applied to the pin. When the shaft is turned all the way in the opposite direction, there are 5 volts going to the pin and the input value is 1023. When the shaft is turned all the way in one direction, there are 0 volts going to the pin, and the input value is 0. The microcontroller of the board has a circuit inside called an analog-to-digital converter or ADC that reads this changing voltage and converts it to a number between. This voltage is the analog voltage that you're reading as an input. When the resistances are reversed, the voltage at the center pin nears 0 volts, or ground. When the resistance between the center and the side connected to 5 volts is close to zero (and the resistance on the other side is close to 10 kilohms), the voltage at the center pin nears 5 volts. This changes the voltage at the center pin. The third goes from the middle pin of the potentiometer to analog input 0.īy turning the shaft of the potentiometer, you change the amount of resistance on either side of the wiper which is connected to the center pin of the potentiometer. The second goes to 5 volts from the other outer pin of the potentiometer. The first goes to ground from one of the outer pins of the potentiometer. Hardware RequiredĬonnect the three wires from the potentiometer to your board. #Analog to digital converter arduino how to#
