Albert Piganti, known as Pighixxx, is well known for his beautiful artwork depicting various microcontrollers like the Arduino and Raspberry Pi, and the various accessories and connections that can be made with them. He is updating his original designs, and
The Arduino UNO has five 10 bit Analog to Digital Converter pins (0-1023), but I needed higher resolution. I’m working with a I2C connected 16 bit 4 channel ADC from Adafruit called the ADS1115. 16 bits of resolution allows me
I have an application that needs two RFID readers. Because these RFID readers are SPI devices, they can be connected to the same two data pins (MISO & MOSI), and clock pin (SCK), and only two pins (SDA & RST)
I needed a Constant Current power supply for my bench. Now I don’t know if you have priced bench power supplies lately, but they can be several hundred dollars. Not any more! Would you believe a 40v 3a adjustable voltage
The whole point of microcontrollers and physical computing is doing something with the data sensed. If you sense a temperature, if you sense motion, you act on it. However, There’s a bunch of science involved when you want to make
Functions allow you to remove repetitive routines from your main code, and call them when needed. There are times when you would like to move commonly used functions out of your Arduino sketch entirely, and into a library you can
