Although you can use this driver without an Arduino library, I highly recommend you also take a look at the example code for theAccelStepper libraryat the end of this tutorial. This library is fairly easy to use and can greatly improve the performance of your hardware. After each example, I...
I used an Arduino Nano as microcontroller paired with a ULN2003 to amplify the signal from the digital out pins for the motor. The motor is a 28BYJ-48 stepper motor. The condensator has 100nF. It turned out that the 5.5V out pin gives me enough current to drive the motor so I connec...
Here is a useful tool to test the working of the Remote handsets used for operating TV, VCD player, and other remote-operated gadgets. These devices use Infrared rays pulsating at 38 kHz and the sensor used is the TSOP 1738 specially designed to sense the 38 kHz IR rays. The circuit giv...
Using 2 resistors and an input voltage, we can create an output voltage that is a fraction of the input. Below you can see the formula that you need to use to calculate the resistors that you need in your circuit: Solving the formula above withVin=5V, R1=1000ohmsandVout=3.3V. We get...
