“This compact Infrared robot controller is based on Arduino Nano and L298 H-Bridge. The Nano shield can be used in various DC Motor driver applications using infra-red remote control or speed controller using trimmer potentiometer and direction control with help …
“The Sweeperino a very useful Arduino based test instrument. It is the following: A very stable, low noise signal generator from 4 MHz to 160 MHz without any spurs A high precision power meter with 90 db with 0.2db …
“I have been working on this project for quite some time. The original idea came to me after building a TEC controller demonstrator at work for a trade fair. To show the TECs heating and cooling capabilities we were using …
“I remember playing a paper and pencil version of the Battleship Game as a kid. In fact, it has been around since about World War 1. I also had an electronic variant in the early 1960s called Sonar Sub Hunt …
“An interesting way to increase sensitivity and reduce the noise of the ADXL335 analog accelerometer. The ADXL335 is a low power, complete 3-axis accelerometer with analog voltage outputs. The product measures acceleration with a minimum full-scale range of ±3 g …
“This is a simple arduino project to make a electronic die. It is possible to choose for 1 to 6 dice or 1 out of 8 special dice. Choice is made by simply turning a rotary encoder. These are the …
“Building a heartbeat detector with infrared. Taking your pulse is as simple as holding your finger to your neck and count the beats with your watch. But if you turn that mechanical pulsing action into an electric signal, you are …
“Make the simplest ISD1700 programmer using Arduino. In one of my recent projects I needed to add voicing the short text messages. Shields likeMP3-module with SD-card seemed to me excessive, and «teaching» Arduino to reproduce human speech would mean …
“A little game to show how a PCF8574 can be used with a Nokia 5110 screen.”
“While I was working on the power meter function for the latest version of the SNA, I used several fixed attenuators for checking linearity and calibration. It would be a lot easier if I had a variable step attenuator. I …
