The robot arm uses three conventional PWM servos, and each angle is controlled by a variable resistor. The rotary potentiometer used B curve 10k ohm.
Two DS3115 servo motors were used in the vertical direction, and MG995 servo motor was used in the swing direction.
After many hours studying Arduino programming and thanks to the support of the Arduino Forum.cc community, the maker MBcreates was able to build his first Arduino project: a digital air pressure regulator. “Simple is often better. So I grab an old blowgun and used this a valve. The Arduino Digital Air Pressure Regulator uses a…
David Pride has taken a Tobbie robot toy and hacked it using some 3D-printed extra parts and a Raspberry Pi Zero. He’s used a ZeroBorg from PiBorg as the motor controller and then 3D-printed a replacement head to house the Raspberry Pi Zero, the ZeroBorg, a Pi camera and a Pimoroni Blinkt for eyes. Predictably now called “Zobbie”,…
We talked a lot about the fight around the Arduino brand. In our post “Arduino vs Arduino: who will keep the brand?“, we analyzed the details of the problem and the vicissitudes that forced Massimo Banzi (one of Arduino’s Creators) to change the name of his board to Genuino. At the end of last…
In this guide, we will describe how the DM Board ICS outputs can be controlled by means of your own voice. Here you can view a demonstration video. Hardware The module EasyVR 3 made by VeeaR is the speech recognition system chosen for this project. The connection of this module to the DM Board…
We place metal foil notes on a panel and play our music by touching them, creating a melody from a truly original instrument. Those who know a little about music or have good memories of the “music education” hours at secondary school (or secondary school, to put it in a modern way), will certainly…
I have a chess computer (not pictured), it’s quite a good way to play longer games at home. It’s hard to find an opponent online to play a game that might last 4 hours, and even if you find one, it’s easy for one side or the other to get distracted or lose interest….
