Now that the PC’s com port or Serial port is almost obsolete there is quite a lot of requirement for USB to TTL or USB to RS232 converter. USB to TTL converters are required for interfacing microcontrollers to PC it is also required for loading code in Arduino Mini, setting/modifying ESP8266 firmware. Over here we […]

“Drone The Quadcopter” is an featured UAV. I design my project with F450 arm in X-mode design. The full operation takes place via a Flysky FSCT6 remote control unit which gives a better operating range of 800 Meter to 1.2KM. If you are a beginner in this field then you are on the right place.

About From USA, Europe, China, and from Japan to India; from the Middle East and Hong Kong, we have been looking to find a creative solution for the most critical issue in electronic design: (PCB Fabrication). When you want to turn your innovation from a mere idea to a real product, you won’t have to

The 555 timer was introduced over 40 years ago. Due to its relative simplicity, ease of use and low cost it has been used in literally thousands of applications and is still widely available. Here we describe how to configure a standard 555 IC to perform two of its most common functions – as a

While most of my microcontroller designs run on 3.3 volts there is still the ocasional 5 volt design. Or I do something with an Arduino. So the need may arise to interface between logic working at different voltage levels. There are several ways of doing this, depending on your needs. Things are relatively simple as

Introduction Vector network analyzer (VNA) are used to measure scattering parameters of high frequency circuits. When frequency is high enough the reflections of the waves start to matter and distributed effects need to be taken into account. VNA can be used to analyze reflection and transmission coefficients of circuits at high frequencies. For example ideally

In the previous posts I’ve described a simple Geiger–Müller counter and various experiments with this device. Today I would like to present Arduino project to communicate with a Geiger-Muller counter, gather data and present it to the user. The device is based on Arduino Uno, Nokia 5110 LCD and homemade shield. Currently it’s possible to

There are two things that you don’t want to do with any rechargeable battery on a routine basis: Overcharge it. Overdischarge it. While the above are true for lead-acid batteries, they are particularly true of Lithium-Ion chemistries, but for different reasons. With Lead-acid batteries: Lead-acid batteries – particularly the “flooded cell” types (e.g. those to

Ok, before to introduce this project, i want to apologize for my English, my native language is French… Secondly, this is my first Instructable, and it’s the first part of a biggest project (a MP3/SD card/USB/radio/bluetooth/clock/alarmclock/temperature/humidity on TFT touchscreen 3.5″) So, I was searching for a tutorial to create a simple Radio with Arduino… And
