This system of Ohm meter based on Arduino is a device or instrument has less complex circuitry and considerable accuracy than conventional Ohm meters. The low value resistors are used in internal circuits of automobiles and other machine where accuracy is the major requirement. This system aims ...
So to improve the accuracy we can plot of set of measured ADC values with actual vales using a known set of values and then use that data to plot a graph and derive the multiplier equation using the linear regression method. You can refer the Arduino dB meter in which I have used a s...
To use this meter with an LCD screen, connect the LCD to your Arduino (seeHow to Set Up an LCD Display on an Arduinoif you need instructions). Pin 11 will be used for the LCD, so wire the capacitance meter using pin 8 instead of pin 11. Here’s the code: #define analogPin 0 #...

You can make temperature and humidity meter using DHT11 and LCD display You can make a simple piano using buttons and buzzer You can make a digital clock using RTC and LCD/Seven Segment. You can also add alarm using Buzzer. Four buttons can be used for time adjusting and configuration. ...
The manufacturer of the thermistor might tell you it’s resistance, but if not, you can usea multimeterto find out. If you don’t have a multimeter, you can make an Ohm meter with your Arduino by following ourArduino Ohm Metertutorial. You only need to know the magnitude of your thermis...

Step 5: Update1: Using a 16x2 LCD Improvements During further testing I realized that the library for the I2C OLED Display was using up considerable time. So I decided to use a 16x2 display with a I2C converter instead. So I adopted the program to the LCD display adding some useful fea...
Our experiment will involve using an Arduino to control a 5-meter strip of RGB LED strip lights. We’ll have three potentiometers to control the intensity of all three colors, allowing us to dial-up a rainbow of colors. You’ll require three MOSFETs or MOSFET Modules to wire this up, ...
