Recently, for my IMU (Inertial Measurement Unit) project, I had the necessity to add low-pass filter, in order to reduce the noise on the accelerometer sensor signal. For this purpose, I decided to use a 1st order IIR (Infinite Impulse Response) filter, because it is easy to implement and run on a microcontroller. In general, … Continue reading "How to calculate a first order IIR filter in 5 minutes"
In this article, I would like to show the analysis which I have done on the ECU installed on Honda CBR125R. One person from France kindly sent me for free this ECU, and I sent him a Fuelino Proto3. Before opening the ECU, it looks as in the following picture. First of all, the following … Continue reading "Keihin ECU on Honda CBR125R"
Recently, for my experiments, I am using an Arduino Nano 3.0 which I bought on Amazon Japan for a cheap price (300 Yen or so). One of the first things that I noticed is that this Arduino, equipped with Atmel ATmega328P microcontroller, unfortunately has only 1 hardware serial port available. For this reason, I decided … Continue reading "SWseriale software serial library for Arduino"
Yesterday I received at home my first Arduino 101 (Genuino 101). I bought it on Yahoo Auctions for just 2,000 Yen. The board has the same size of an Arduino Uno, Ethernet and similar. But, instead of an Atmel microcontroller, it uses the new Intel Curie architecture. The frequency increases from 16MHz to 32MHz. The … Continue reading "Arduino 101 has arrived"
