What do you need to build an Arduino Speed Sensor Building an Arduino speed detector using IR technology to measure the speed of a moving object is much more cost-effective, and it is also very simple ...

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, ...

After some searching, I ended up using a microcontroller and a piece of code borrowed from the web that I tweaked and adapted. The microcontroller-based concept was chosen because I wanted to scale ...

Arduino code for Bidirectional Counter System The complete code for a Bidirectional counter system using Arduino is given below. It continuously checks for which sensor gets triggered first. It then ...

As much as we love the Arduino Uno, it's not the most powerful of hobbyist microcontrollers. Fortunately, the folks in Turin have just put the finishing touches on a 32-bit upgrade with buckets of ...

This build is about using the temperature sensor in your clock. The ATMega328p, the chip at the heart of all your Arduino Uno clones, has within it a watchdog timer that clicks over at a rate of ...

This sensor is built for detecting ppm of certain gas molecules, such as VOC, ethanol, ammonia, Hydrogen sulphide, etc. This sensor can't distinguish different gas molecules. Please use the table ...
