This project uses the Arduino Uno PWM output to realize a fully isolated analog output with a range of 0..5 V or more. The use of an averaged PWM signal is not comparable with a real DAC, but it has ...

The purpose of this project is to provide a 4-20 mA output from a PWM signal generated by a microcontroller. One of the more interesting applications of this circuit would be to replace or to realize ...

There are so many nice hacks in [Joekutz]’s retro LED display project that it’s hard to know where to start. There’s his DIY LED display controlled by an Arduino UNO. To have some text or picture for ...

If you are designing your own intelligent “Graden Computer” with an optional digital plant moisture sensor/water pump controller that lights an LED to alert the user when it is time to water a potted ...

Light sensors are widely used in electronic applications. The most common one used is a photoresistor or light-dependent resistor. Despite a long response time, this sensor is inexpensive and useful ...

The damages that can be done by fire are devastating. To prevent causalities or damages, it is necessary to detect the fire, so that warnings can be provided and even automatic fire suppression ...
