This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...
Use an ATtiny85 to display sensor values on an I2C LCD (equiped with PCF8574): GY21P (Si7021+SHT21) I2C sensor, temperature and relative humidity DS18b20 Dallas sensor, one wire, temperature I had ...
One of the limitations of the small 8 bit microcontrollers like the Atmel ATMega family adopted by the Arduino board, is the reduced number of I/O ports. Among the main advantages of these ...
Today, We will review the Cytron Maker Uno RP2040 development board combining the Arduino UNO form factor with the Raspberry Pi RP2040 microcontroller that makes it programmable with the Arduino IDE ...
