12/7/2023 0 Comments Arduino piezo code![]() Unlike arduino ADC the arduino pwm provides 8 bit resolution.Buzzer and LED will operate only on the voltages greater than 1.5 volts. The if statement in the code is checking 1.5 volts or 310 integer value by ADC. When the voltage across 10 k resistor increases 1.5 volts(ADC value 310) then the buzzer and led are activated and are driven with the same voltage that appears across the 10 k resistor. The same above strategy is applied in the code. So if voltage across the 10 k resistor is 2 volts than the analog channel 0 of arduino will read it and provide us an integer value of 410. ![]() Arduino ADC(Analog to digital channel) is 10 bit wide or its resolution is 10 bit.
