It’s not that unusual to have ADC offsets. Sometimes vendor code hides it (PSoC), sometimes it’s in full view of everyone (ESP32). Sometimes you just have to do something tricky like running ...

The build relies on that old stalwart, the Arduino Uno, to run the show. It’s hooked up to a DS3231 real-time clock module so it can keep accurate time for long periods, as is befitting a clock.

The junction on the voltage divider network connected to the the Arduino analog pin is equivalent to the input voltage divided by 11, so 55V ÷ 11 = 5V. In other words, when measuring 55V, the Arduino ...

Prestissimo Uno+ Arduino dev board with extra I2C UART SPI ADC IO and PWM channels. 2:24 pm November 5, 2018 By Julian Horsey.

Here is an Arduino experiment with a famed linear active thermistor chip MCP9700A from Microchip Technology Inc. The chip comprises an analog temperature sensor that converts temperature to analog ...

We’ve taken the versatile processor behind the Arduino Leonardo, and combined it with a Direct Digital Synthesis chip, which makes generating analog signals incredibly straightforward.

The analog input pins on the two microcontroller boards are also somewhat similar. They both have 10-bit resolutions that can read values of up to 1024, and their A4 and A5 pins both double as SDA ...
