What if I told you that you could build a display out of shoe laces!? Well that is exactly what I’ve done! Building your own seven segment display is nothing new, it’s a very common Arduino project, but I had an idea for this one so I said I’d give it a go, and I

Let’s learn how to read a photoresistor, a light-sensitive type of variable resistor, using Arduino’s Analog Input. It’s also called an LDR (light-dependent resistor). So far you’ve already learned to control LEDs with Arduino’s analog output, and to read a potentiometer, which is another type of variable resistor, so we’ll build on those skills in this lesson.

LEDs are designed to emit light, but they also make surprisingly capable sensors. Using only an Arduino UNO, an LED and a resistor, we will build a hot LED anemometer that measures wind speed, and turns off the LED for 2 seconds when it detects you are blowing on it. You can use this to
An LED You Can Blow Out Like a Candle! Continue Reading
For this assignment, your goal is to transform the Arduino into a thermometer! Utilize a temperature sensor to track your skin’s temperature and record the information using three LEDs. The Arduino, being a digital tool, is able to collect information from analog devices such as the TMP36 temperature sensor by utilizing its on-board Analog-to-Digital (ADC)

In this project I will show you how I combined an Arduino Nano, a current sensor, an LCD, a rotary encoder and a couple of other complementary components in order to create an adjustable constant load. It features a constant current and power mode and can handle a maximum of 30V and 20A if your

If you have kids, you are likely facing the same issues as we did with the Lego sets you bought for them. They assemble and play with them but after a while the sets transform into a single pile of bricks. The kids grow up and you don’t know what to do with this pile.

Let’s measure distances with an ultrasonic rangefinder (distance sensor) and Arduino’s digital input. We’ll connect up a circuit using a breadboard and use some simple Arduino code to control a single LED. You may have already learned to read a pushbutton and PIR motion sensor with Arduino’s digital input, and we’ll build on those skills in this lesson. Ultrasonic

Bored of keeping track of countless locks and their keys? How about using your own fingerprint to unlock each and every safe in your house, just like your Smartphone? Sounds cool, right? Let’s make an electronic Fingerprint locker that will keep all your secrets a secret from your enemies. And not only one, but up
