Making Arduino Uno Bootloaded IC

This post is intended for the Arduino hackers, who need to make bootloaded Arduino ICs. The fuse bit settings and hex files used are for Arduino Uno R3, but the same method can be used for any Arduino board. Fresh ICs cannot be used directly to replace Arduino ICs, but with some bootloading techniques it can…

DHT11 Temperature and Humidity Sensor Interfacing

  DHT11 is a low cost Temperature and Humidity sensor which can be used for less precise application, but has a decent range of operation and sensing. Also no external calibration is required, as it has inbuilt calibration done in production laboratories, also it require minimal external components for interfacing.   The above figure shows the Arduino interfacing…
