Connect the 3V line to the top of both pots.Connect the ground line to the bottom of both pots.Connect the left pot's center pin to X oscilloscope input.Connect the right pot's center pin to Y oscilloscope input.
Optocouplers = PC817 Resistors = 210 Ohm Note the opposite direction of X vs Y connections to the optocouplers due to the opposite direction in current flow.
Some sensors of the smartphone can also be used with Blynk. This time I wanted to use its accelerometer to control my robot. Tilt the phone and the robot will turn left/right or move forward/backward. Drag accelerometer object from Widget Box and drop...
Using RT=D we can algebraically rearrange the equation to get R=D/T, or Terminal velocity equals Altitude divided by time. Since we have Altitude and drop time, from one measly data point, 350 ft and 4s, we can figure the rate, terminal...
I'm using the 5MP Pi Camera which has a fairly easy setup. Just enable camera in settings and connect the camera to the port (the one opposite to Ethernet input) with its blue part facing the Ethernet. RPi camera module setup For the Smile detection...
Make Processing control Arduino THE FINAL PROGRAM:So,you have started drawing on Processing. Now, you'll 'feel' the drawing!Imagine you are blind (remember, this device was invented for blind people to draw on computers):How would you feel a raised line...
1. Plug the 28BYJ-48 Stepper Motors in to the ULN2003 stepper Drivers. one will be used to roll the paper along the y-axis and one will be for moving the 'print head along the x axis. 2. Connect the x axis driver to the arduino from its pins...
This green piece join the two structures. With the hole for the linear bearing in the bottom part and the space for the corner pieces in the upper part. With four of this green pieces and four linear bearing we can join the two structures and can move...
Connection for the buttons can be seen in picture below:U,D,L,R are directional buttons (Up, Down, Left, Right)A,B,C,X,Y,Z are buttons (SNES nomenclature)Sl,St are also buttons, named after SELECT and START (also SNES nomenclature)
I inserted 2 power plugs directly inside the cabinet controlled by a switch. One plug will power the screen while the other powers a 5V adapter for the Pi and the amplifier (you’ll need to cut the one side of the Y USB cable to power the amplifier)....
2.1 Raspbian with latest updates Install onto SD card using Win32DiskImager or as preferred Connect to Orbit Externet and run sudo apt-get update Change the timezone using sudo raspi-config and navigating to the appropriate...
I started by thinking of a free-wheeled machine that could have an infinite Y-traverse, but it proved to be too cumbersome and inaccurate.So I chose to use V-slotted rails with wheels instead. I then went on Fusion and designed several parts, including...
The code is pretty simple. You can set the X and Y limits for your servos and tweak the sensitivity. It's not too complex overall. People often ask us if there is some way to make the servo movement smoother. They're servos so there really isn't...
