wired(obniz, {[scl, sda, vcc, gnd, i2c]})

connect to the obniz Board.
When using M5StickC, You do not need to assign pins.

// JavaScript Examples
var adc = obniz.wired("M5StickC_ADC");
while(true) {
  var vol = await adc.getVoltageWait();
  console.log(vol + " V");
  await obniz.wait(1);
}

When using other devices, assign vcc and gnd as appropriate pins.

// JavaScript Examples
var adc = obniz.wired("M5StickC_ADC", {sda:0, scl:26});
while(true) {
  var vol = await adc.getVoltageWait();
  console.log(vol + " V");
  await obniz.wait(1);
}

setGain(number)

Setting a gain. Choose from 1(default),2,4,8 times.

// JavaScript Examples
var adc = obniz.wired("M5StickC_ADC", {sda:0, scl:26});
adc.setGain(1);
while(true) {
  var vol = await adc.getVoltageWait();
  console.log(vol + " V");
  await obniz.wait(1);
}

[await] getVoltageWait()

get the potential difference(V).

// JavaScript Examples
var adc = obniz.wired("M5StickC_ADC", {sda:0, scl:26});
while(true) {
  var vol = await adc.getVoltageWait();
  console.log(vol + " V");
  await obniz.wait(1);
}
