[SeanHodgins] has a project in mind where he needs to sample over 500 analog sensors. To get ready, he made a breakout board for 32-channel analog multiplexer device he wants to use. He put the ...

When it comes to educational electronic projects, it’s hard to go past building a clock. You learn tons about everything from circuit concepts and assembly skills to insights about the very nature of ...

I have started this joystick controller experiment inspired by the need of a simple DIY joystick which could deliver greater flexibility in the possible designs. Hardware component basis is very ...

The project illustrates the driving of analog meters using PWM outputs from Arduino as well as the LCD Smartie program. A small current is typically required by meters to operate wherein a typical ...

pin 23 PC0/ADC0 (arduino analog 0) - potentiometer for pwm 1. Leftmost slider pot. pin 24 PC1/ADC1 (arduino analog 1) - potentiometer for pwm 2. Rightmost slider pot. pin 26 PC2/ADC2 (arduino analog 2 ...

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 ...

VCC is the power supply pin of the soil moisture sensor that can be connected to 3.3V or 5V of the supply. But do note that the analog output will vary depending on the provided supply voltage. GND is ...

This short article describes a simple circuit capable to convert a TTL/CMOS PMW signal to an analog signal. The circuit can be used as an extension shield for Arduino with a simple MCU or with ...
