LED Signal Level Indicator Module for Arduino Projects
One output GPIO pin is directly connected to the Water Level Sensor and sends a 3, 3 V signal to the sensor with a duration of just 200 milliseconds. The 5V power for the 5 LEDs used in the Level Indicator is derived directly from the 5V pin (connected to the 5V input from the USB port); ARDUINO Sketch for DIY Water Level Sensor and DIY
How to Build a Liquid Level Sensor Circuit with an Arduino
1/5/2016My dad made a turn signal light set up 20+ yeas ago for a moped that he just handed down to my daughter. She got caught in a rain storm and the blinkers quit working. I was just thinking of using an Arduino to rebuild the setup.
Arduino Playground - Waterlevel
I am a newbie and have followed a tutorial to build a battery level indicator as below Please suggest any changes I'll need to make to make the circuit useful with a 48V battery as the above circuit is tested with a 12V one. Thank You.
I have built a battery level indicator and have tested

The function used to output a PWM signal is analogWrite(pin, value). pin is the pin number used for the PWM output. value is a number proportional to the duty cycle of the signal. When value = 0, the signal is always off. When value = 255, the signal is always on. On most Arduino boards, the PWM function is available on pins 3, 5, 6, 9, 10, and 11.

Measure Sound/Noise Level in dB with Microphone and Arduino Arduino. By Aswinth Raj Jan 04, Circuit for this Arduino Sound Level Meter is a very simple in which we have used the LM386 Audio amplifier circuit to amplify the signals from a condenser microphone and This AC signal might have some DC noise coupled with it which will be
