Water detector with 4 level stages. Each stage makes the 555 timer to give a supply period for the buzzer. The active buzzer transmits sound with a pause period between 0.5-3 seconds, depending on the level detected.

This is really a cool little device that not only allows you to measure current, but voltage as well. With a little multiplication, you can even measure power.
In terms of voltage, you get to blow right past the Arduino 5 volt limitation. In fact, you can measure up to 26 Volts DC.
At +/- 3.2A, current measurement range is suitable for most smaller measurements. In other words, you can measu...
This includes all of the electronics for the go-karts used for http://evgrandprix.org/ races. This includes a general schematic for the go-kart itself, a schematic for the "PEM Box", and a previous design concept that has since become obsolete.

**Description**: The INA169 is a “high-side current monitor,” which means that you place a resistor (a “shunt resistor”) on the positive power rail and the INA169 measures the voltage drop across that resistor. The INA169 outputs a small current based on the measured voltage drop. If you place a resistor from the output of t...

**Description**: This is a breakout board for the fully integrated Hall Effect based linear ACS712 current sensor. The sensor gives precise current measurement for both AC and DC signals. Thick copper conductor and signal traces allows for survival of the device up to 5 times overcurrent conditions.
The ACS712 outputs an...
This circuit uses the Buck/Boost Converter circuit for typically for use in a lab bench power supply. It features both adjustable voltage AND current using potentiometers.
Without a buck/boost converter,a computer power supply can only provide a 3.3V, 5V and 12 supply lines. With the buck/boost converter created with the aid of a 555 timer, adjustable voltage is allowed. A simple transistor is us...

**Description**: This current sensor gives precise current measurement for both AC and DC signals. These are good sensors for metering and measuring overall power consumption of systems. The ACS712 current sensor measures up to 5A of DC or AC current. We added an opamp gain stage for more sensitive current measurements. By a...

**Description**: Odometers are extremely useful for cars, they tell you how far you have gone, wouldn’t it be nice if you were able to have a device that does the same for electrical current? The LTC4150 SparkFun Coulomb Counter Breakout is here to be your odometer for current. If you are wondering: a coulomb is defind as, t...
