PLD (Part 4)

Part 1, 2, 3, 4, 5, 6 Using the HL2 PLD (Place and Leave Device) is easy and usefull. We ran the earliest tests on… soil moisture. The reason why we chose this one is that I have always liked to have a green plant in my office and this one might last longer than the others. Because it is fitted […]

PLD (Part 3)

Part 1, 2, 3, 4, 5, 6 The name PLD stands for “Place and Leave Device”. The original design is big enough to encapsulate its power reserve, the radio module, an arduino ™ microcontroller which will run your own code, and connectors for programming, debugging or plugging sensors. The radio module features the HL2 stack which handles data in terms of […]

Ultrasonic scanner (Part 2)

Part 1, 2 Most of the electronic diagram shown here should look familiar to the readers of arduinoos posts. The ultrasonic sensor is added to what was described as the test bench for stepper motors. Here is the list of the required components: An Arduino UNO baord (Should I introduce it to you ?) A […]

Raymond McNamara from the NUI Galway committed his final year works to “Embedded Implementation of Embedded Algorithms of Power System Monitoring” Quality of AC power is definitely a contemporary problem. Many disturbances are generated by the variety of power sources including, and the list is non-exhaustive, solar power, wind power, hydroelectric power. Harmonic frequencies in the […]

MicroFAN (Part 2)

Part 1, 2, 3 Let’s talk about some basic electronics. MicroFAN is really easy and requires few affordable electronic components: a 12V fan, Arduino (Uno, Nano, etc.), a 8×2 LCD (a 16×2 LCD will do the job too), a rotary encoder, typically a 30 pulse 15 detents per round (so as to say 1 cycle per […]

MicroFAN (Part 1)

Part 1, 2, 3 We gained quite a lot of experience after printing few kilometers of ABS on our Makerbot 2x. Controlling the temperature inside the cabinet solved a lot of problems. After few attempts, we decided to modify the printer by adding a fan on top of the transparent cover. The fan is turned […]

Publication of the day

Students from the Vaughn College, Flushing, NY, USA published a very interesting paper  on Aid Device for Deaf Drivers. [Download here]. They use FFT in order to extract specific sounds such as honks from a noisy environment in order to trigger a vibrating device located in the drivers’s seat. As they used some of the information published on arduinoos.com, […]

Pending publications

Summer is over. Apparently a lazy period of time, in reality, time for retrospection, thoughts and projects making ! For me it has also been a time for getting inspiration from various European places, other ways of living, travelling, enjoying arts and culture. Whoever will identify this place will get… my highest consideration ! [Mail] […]

Range finder (Part 2)

Part 1, 2 As in most arduinoos posts, the examples given here differ from what is usually seen and read in terms of  code efficiency  and ruggedness of applications. Early tests performed on the HC-SR04 module proved its easiness of setup and interesting results obtained from scratch. However things are changing when accuracy is concerned and headaches […]

Engine RPM (Part 5)

Part 1, 2, 3, 4, 5 The last two posts explained how to check whether the speed of a rotating object agreed with a predefined value or not. To the cost of an additional optical sensor and a display, we may now measure any rotating speed still without contacts between the moving object and the […]
