Arduino Uno reads MCP3208 ADC voltages on breadboard

Arduino MCP32008 12bit ADC using Arduino Uno with Proteus Simulation

Introduction The Arduino MCP3208 12-bit ADC project is a simple but effective example of analog data acquisition using an external ADC. In this design, an Arduino Uno communicates with the MCP3208 12-bit ADC through SPI and reads multiple analog channels from the simulation inputs. The measured data is converted into voltage values and printed to […]

Connect several digital inputs to one analog input using Arduino

I often run out of digital pins on my Arduino. Anything as complicated as, say, a video game controller, was near impossible with the amount of pins I had available. Multiplexing buttons works, but it requires lots of connections and soldering. So, I put together a solution! Step 1: Resistor Dividers in Five In a
