Sensors are one of the crucial things when it comes to building projects/robots. Many a times the sensor might be not available locally or it might take too long to ship. Smart phone have most of the basic sensors like proximity, accelerometer, light, magnetometer, gyroscope, etc. embedded and we can in fact use these sensors

Serial communication was once the most widely used method of transferring data between computers. Many computing devices that you have used over time employ serial communication. Some of the terms associated with this type of data transfer are FTDI chip, COM interface, the RS232 protocol, and serial port. Serial communication refers to data that is

Story Behold: the MorseCard! Fulfill your dreams of becoming a telegraph operator (or just make something cool to show your friends) with this weekend project. The MorseCard features a high-contrast OLED screen that will decipher whatever you tap out. I have written a variety of different sketches for the MorseCard, as the video above shows,
MorseCard – A Tiny Telegraph Station Continue Reading
Introduction The Atmel tinyAVR MCU’s are great little chips for projects but can prove difficult to debug. Some ATtiny chips do not have direct support for hardware based serial and therefore the Serial object is unavailable in your code, however, it is easy to add a Software Serial object and view output in the Arduino
Easy Serial on the ATtiny Continue Reading
I have a device which provides a USB port. If I attach it to a Windows PC it is recognized as a “CP2103 USB to UART Bridge Controller”. According to the device documentation, it should communicate in serial format at 38400bps.I have to talk to this device with a atmega microcontroller. Since the USB pinout
In this post I’d like to describe you a project I’m working on that consists of connecting an Android development board to one (or more) Arduino slave(s) using modbus protocol and rs485. Even though the idea of this project could be applied in many fields, I chose to contextualize it in a typical smart home
