Tevo Tarantula Z- Axis Nut Fix
Fixing Tevo Tarnatula 3D printer Z Nut holding plate. The printer is working this 3 mm acrylic Z-nut mount. A limit switch miss resulted this:
Permanent Solution to this problem is a aluminium mount for the Z-axis nut.
Start with aluminium angle
Drilling the holes

Arduino Interface for Alcohol (MQ-3) Sensor
Alcohol sensors are commonly available these days and a simple breath analyzer can be constructed using an Arduino board. This alcohol sensor MQ-3 has digital as well as analog out pin. For a quick implementation digital output can be used. Only a bunch of things are required for the interface..

Testing Robotic Arm motor with Arduino + L293D
Arduino provides very simple approach for many interfaces. This is a beginner’s tutorial of testing a robotic arm with arduino board and driver IC. As arduino itself cannot deliver the required current to motors a driver is required. The robotic arm in this experiment uses DC gear motors that can be easily drive using the well-known L293D driver. L293D is basically a quadruple Continue reading “Testing Robotic Arm motor with Arduino + L293D”
