I have worked most of my adult life with patients with vision problems in Alaska and pondered building a helpful device that would enable a more defined way of metering out fluids in a kitchen if users had no central vision. There are devices already for defining the limits of a cup with two wires

Match a stepper motor to external driver hardware: unipolar versus bipolar wiring, supply and current budgeting, and verifying coil documentation first.

a simple 3 buttons on-off with pic12f629. it’s written with MikroC Step 1: The Code… start the code with ”int”———————————————————- int x0,x1,y0,y1,z0,z1; ////// with this the GPIO outputs could stay on or off void main() { GPIO = 0x00; ////// all outputs are 0 CMCON = 0x07; ////// Disable CMCON PORT TRISIO = 0b00111000; //////

In the previous instructable I showed you how to get started with IoT using the nodeMCU, in this instructable I will be featuring the Particle Photon which is an easy to use IoT device to get started with designing IoT projects. The particle photon is smaller than the nodeMCU and features STM32 ARM Cortex M3 microcontroller on

Schematic Since the IR Sensor uses a light sensor, the schematic is very similar to that of the light sensor. The only difference is the addition of an IR LED and that the IR detector requires connection to 5V and ground. Breadboard Setup To setup the sensors you will need: 2x IR Detectors 2x IR

The DJ Touch is a portable turntable touchscreen and interactive LED display. Our end goal was to produce a low cost touchscreen device, and demonstrate its application in a common consumer application. Out of an interest in electronic music, and with the knowledge of deejaying’s close roots to electronics, we decided to develop a touch

One of the simplest ways to get a motor to turn in both directions is by using a double-pole, double-throw (DPDT) relay. Along with the relay, this hookup requires two transistors and two Stamp pins, one for on/off control and the other for direction control. The diagram below contains the schematic for this setup. The

Let’s get the math over right off the bat. There are a LOT of attempts to describe how Ohm’s Law works, each one nerdier than the last. Here’ one I like. Warning: SFWBN (safe for work but nerdy). V = voltage measured in volts – the difference in electrical potential. I = Current measured in

We created an Internet-enabled companion cube for your computer, which displays different kinds of information by glowing red or green. Depending on its orientation, and which labeled face is oriented upwards, our companion cube displays either stock readings of the NASDAQ or the outside temperature in Princeton. As the temperature or stock index changes, the

The assignment for this week is to automate the machine assembled two weeks ago. For this Roxanna milled the Arduino’s shield for controlling the steppers, but Alejandro found that we haven’t all the components for stuffing, specially the A3982 – stepper motor driver, so as was impossible to get it locally, I decided to design
