While the Arduino MEGA does have more built-in GPIO pins (70 digital input/output pins, of which 14 can be used as PWM outputs and 16 can be used as analog inputs), it's pretty old tech now, and if ...

Becky Stern and the Digi-Key YouTube channel have created beginners overview video of Arduino inputs and outputs. Providing a 10 minute overview of what you can use the range of microcontroller ...

The Sensact Hub brings together 3 analog inputs (one of them can be configured as an I2C input) and 2 relay outputs as well as HID, IR and Bluetooth outputs. We use 3.5mm audio sockets to make it easy ...

Input/Output There are three interface points to the Arduino. The PWM output is set as an external voltage using the “Inputs and Sources” components (remember, the output from the Arduino is ...

Today more and more systems are incorporating microprocessor controllers into their design. Troubleshooting the operation of these controllers can be a little tricky at times, but if broken down into ...

Most Arduino boards have an ADC chip with a 10-bit resolution that can output values from 0 to 1023. Popular boards like the Arduino Uno, Nano, Micro, and Mega are great examples of this.
