Testing the DHT11 Sensor

Posted by Marius Cloete on

What you will need : DHT11 sensor Male to Female wires UNO board   First, we need to download and install the DHT-sensor-library. https://github.com/adafruit/DHT-sensor-library "To download. click the DOWNLOADS button in the top right corner, rename the uncompressed folder DHT. Check that the DHT folder contains DHT.cpp and DHT.h. Place the DHT library folder your [arduino IDE install directory]/libraries/ folder. You may need to create the libraries subfolder if it is your first library. Restart the IDE."   Next, connect the sensor to the UNO board VCC to 5volt Ground to Ground (GND) Data to PIN 2   Connect you...

Quick start CNC shield v3 for Arduino (Part Two)

Posted by Marius Cloete on

This continues from the previous tutorial quick start CNC shield v3 for Arduino for this tutorial, we will be using the following hex file:  Grbl v0.9j Atmega328p 16mhz 115200baud with generic defaults (2016-03-17)        IMPORTANT INFO WHEN UPGRADING TO GRBL v0.9 :        Baudrate is now 115200 (Up from 9600).        Homing cycle updated. Located based on switch trigger, rather than release point.        Variable spindle is now enabled by default. Z-limit(D12) and spindle enable(D11) have switched to access the hardware PWM on D11. Homing will not work if you do not re-wire your Z-limit switch to D12.   The main thing to note...
