[...] which is of great use for a beginner. For those interested in the project, everything from source code to hardware-description is available on the website along with some example programs that can [...]

[...] approximation algorithm’. He writhes a thorough explanation on how it works and provides source code to try it out. Currently such ADC was able to generate 750 samples at 8-bit resolution which is [...]

[...] to receive and send message packets in API mode. For those who want to dig deeper, there is a source code available in Github. [...]

[...] Arduino IDE is so much hated editor by many programmers. When it comes to bigger source code, complex algorithms – managing it becomes pain. People usually go with it and waste time or [...]

[...] something new to you, that just like MSP430 some of the ATMEGA devices also has an inbuilt temperature sensor. This could be read by using an in build ADC with certain settings. Majority of the new [...]

[...] id BMP180 barrometric pressure sensor which can be used as altimeter. It also includes temperature sensor. Going further there is well known DHT22 Temperature/humidity sensor which measure humidity [...]

[...] be refilled with water to keep humidity at level. Dzzie decided to add DHT22 humidity and temperature sensor to it and along with Arduino log this data to webserver. He wrote a PHP script that records [...]

[...] ) control voltage. Microcontroller reads sense voltage from MCP3204 ADC. There is also a temperature sensor on heatsink which keeps an eye and turns fan if things get hot. Key parameters of load are: [...]

[...] fan of DIY scopes that are built of microcontroller and LCD or interfaced to PC via serial interface. You will never get decent sampling and functionality with low end parts. But in other [...]

[...] this saves time while entering. He used parallax RFID readers that can be communicated via serial interface. Control boards are custom built Arduino where Atmega328 gets data from RFID readers and [...]

[...] your code. Other covered option is using built in bootloader which can be accessed through serial interface. ST have special software Flash Loader Demonstrator for programming in this mode. When [...]

[...] Atmega328p microcontroller which reads all sensor data and then can send it through I serial interface. He made 6 pin header to accept standard FTDI interface module. PCB was fabricated by using [...]

[...] popular sensors are laser module, infrared barrier, sound, flame sensor, line tracking, rotary encoder, digital temperature sensor, RGB LED, various switches like mercury, tilt, button, [...]

[...] rotating object stationary. He grabbed Arduino Nano and put his circuit that includes LCD, rotary encoder for changing frequency, also he added four buttons for fast frequency halving and doubling in [...]

[...] using TLC5916 LED driver and couple dual P-channel MOSFETs. Time can be selected with rotary encoder which comes with button for select. When timer runs out there are two options for [...]

[...] building three PCBs where one is a control board carrying LCD, PIC 16F648A microcontroller, rotary encoder and push button. Other two boards are resistor boards – one for high value resistors and [...]

[...] old school. Building one isn’t that hard. Tom has been building one around Atmega328P with Arduino bootloader. His clock uses six IN12 nixie tubes along with 74141 driver chips. Data to digits are [...]

[...] seeing action on Nokia 5110 graphical LCD . He built all PCBs from scratch leaving only Arduino bootloader on Atmega328 microcontroller. He wanted game device to bee convenient to handle but still [...]

[...] interesting used of USBASP – he turned it in to Arduino. What he did – he flashed Arduino bootloader in to Atmega8. A J2 jumper allows same header for programming chip itself. After he [...]

[...] Development Labs have built reliable gearshift indicator. They used AVR micro with Arduino bootloader. Most challenging part here is to read gear data from mechanical gearshift. The room was [...]

[...] -06 and HC-05, and Nrf24L01+. Board can sit on top of Arduino Uno as shield or be as base for Arduino Pro Mini along with FTDI programmed adapter. All those adapters already have Arduino libraries [...]

[...] also has a timer for turning devices on or off after some time. Outlet is controlled by Arduino Pro Mini. Load is switched with mechanical relay module. IR function is implemented with Keyes IR [...]

[...] similar to original one so he started an Arduino based BMO. Central brain if it is Arduino Pro Mini with Nokia 3310 LCD screen. He placed all components in to nice custom 3D printed box, [...]

[...] with PID system. This can be fun to learn and explore. So he came up with small robot carrying Arduino Nano, 3 potentiometers, 6 DOF IMU. All electronics are mounted on custom PCB once mounted, burn [...]

[...] , they laser cut nice acrylic enclosure that makes this clock stand out. Clock is powered by Arduino Nano. Even if displayed time accuracy is half an hour, internal time is kept precisely with [...]

[...] to adjust light beam flashing frequency until you see rotating object stationary. He grabbed Arduino Nano and put his circuit that includes LCD, rotary encoder for changing frequency, also he added [...]
