The objective of this project is to build an Arduino voice shield to empower thousands of voice related applications! All this mostly thanks to an integrated ISD1790PY chip. This particular voice/TTS feature can be useful to integrate voice messages in alarm systems, to implement generic I/O controls in home automation or even in home security …
Seven segment LED displays and discussed about a time-division multiplexing technique that reduces the number of required microcontroller I/O pins to drive multiple seven segment LED displays. Today we will move a step further and discuss about a serial interface (SPI) for driving 8 seven segment LED displays. The technique uses MAXIM’s MAX7219 LED driver …

DIN rail terminal blocks using the CAGE CLAMP®S spring clamp bring a simpler installation even without tools and up to 30% saving of space. Since 1977, when company Wago launched screw less terminal blocks on the market, have the terminal blocks using this system earned a high popularity. During many years, the Cage Clamp® system …
EA DIP series displays from company Electronic Assembly provide an uncommon possibility to choose a graphic or a character display without a change of your device´s hardware. A quality display with a high contrast and an automatic temperature compensation, easy mounting by soldering of pins into a PCB, a display maximally utilizing the module size …
The difference between insignificant noise and significant noise is the degree to which the noise affects the operation of the circuit in question. For example, a switching power supply has a significant amount of output voltage ripple at 3 MHz. If the circuit it is powering has a bandwidth of only a few hertz, such …
One of the basic usage of the TIMER peripheral on every microcontroller is to provide the accurate timing mechanism. Using the TIMER peripheral as the basic timing, we could easily develop a stopwatch and display it to the 8-Digit seven segment numeric LED display. Thanks to the Maxim MAX7219 chip which enable us to interface …

The TV transmitter we present today generates a stream containing four TV programs and broadcasts it on a frequency in the DTT standard . Ideal for stacking in an antenna system, audiovisual channels generated on-site or from other sources like a decoder for satellite television. With this project you can make a small local TV …
This is a simple project of Android Bluetooth Car with Bluetooth control. This project is open source and multiplatform: Adriano (Processing), STM32, MSP430, PIC, AVR, FEZ Panda II (.NET Micro Framework) and may be even В Raspberry Pi. To control the car used Android-device with a built-in accelerometer. Tilt forward – car goes forward, tilt …
