How does the security alarm circuit works? When power is turned on, the circuit goes into standby mode, and this condition is indicated by “SECURITY ALARM” in the LCD screen.Note that here a N/O reedswitch + bar magnet combination is used to detect any mishaps, and hence the reed switch should be in “closed”state at …
In present time almost all the people are familiar with robots. Robots play a very important role in human life. Robots are a machine which reduces the human efforts in heavy works in industries, building etc. and makes life easy. We are here with our next robot that is Mobile or DTMF Controlled Robot. DTMF controlled Robot runs …
The new design of the 6WD mobile platform, the vehicle uses 2mm aluminum alloy, aluminum spray surface treatment. 6 high-speed DC motor (original 17000 rpm), with 1:34 full metal gear box, so that the car to obtain strong off-road performance. Shock absorption design is the highlight of the car, the use of 6 damping shock …
bOunce is a haptics-based learning game system that teaches the concepts behind wave dynamics, and in particular, resonance. The bOunce device (an adaptation of the Haptic Paddle) allows a user to “bounce” a ball in a virtual environment. By feeling the haptic force feedback from the virtual ball, as well as seeing the ball’s waveform trajectory …
The post explains how to build a simple sinewave inverter circuit using PWM feed from an Arduino Uno board, the article also discusses a sinewave 3 phase inverter using the same input from an Arduino. The idea was requested by Mr. Raju Visshwanath Technical Specifications UPDATE: Please also refer to this article which explains how …
Although nowadays many portable devices (smartbands, smartwatches, smartphones,…) are available that can detect the Heart Rate (HR) and perform trace analysis, chest strap belts-based systems (like the one in the upper part of thr picture) are still widespread and used, but lacking the possibility to record and export the trace of the measurements. In my …
Finally, I finished reading the datasheet. It didn’t give much information about how to connect the motor controller to a micro-controller. I used the simple circuit I found from a post in Pololu’s forum: Using Dual VNH3SP30 Motor Driver with arduino @ http://forum.pololu.com/viewtopic.php?f=15&t=1923. Dual VNH2SP30 Motor Driver Carrier MD03A to Arduino Circuit Diagram I connected everything …

When we first released our 3D printer, we tried to use some parts that were already available and tested, in full respect of the open source philosophy. In particular, we decided to use the electronic card Sanguinololu. The “open” firmware we chose, the Marlin firmware by Erik van der Zalm, solved the biggest part of the computer interface issues. …

Viseesaw uses the figure of a seesaw, to show metaphorically the inequality of two physical, conceptual or social realities. Things used in this project Hardware components Arduino MKR1000 × 1 Breadboard (generic) × 1 Adafruit Motor/Stepper/Servo Shield for Arduino v2 Kit – v2.3 × 1 Adafruit Stepper motor – NEMA-17 size – 200 steps/rev, 12V …
