For those who have a keen interest in gardening, a garden light would provide an option to admire the beauty of their plants even during the night time. These lights will normally be placed inside the garden, far from electrical outlets because it is not a good idea to run wires through your garden soil which will be wet and toiled most of the time. This is where Solar-powered garden lights come into the picture. These lights will have a battery that will be charged through a solar panel in the day time and during the night time the energy from the battery will be used to power the lights and the cycle repeats
This DIY Arduino CNC Machine can draw most of the basic shapes, texts and even cartoons. It’s operation is similar to the way a human hand writes. It’s faster and more accurate compared to the way a human being can write or draw.
For a CNC plotting machine to operate, 3 axes are required (x-axis, y-axis and z-axis. The x-axis and y-axis work in unison to create a 2D image on a plain paper. These x and y axis are placed 90 degrees to each other such that any point on the plain surface is defined by a given value of x and y. The z-axis is used lift and lower the pen onto the plain paper.
Depending on the image to be drawn, the computer will generate the appropriate coordinates and send them to the microcontroller through the USB port. The microcontroller interprets these coordinates and then controls the positions of the motors to create the image. Here we have used Arduino as the Microcontroller to build this CNC Machine.
In this project, we are going to use NodeMCU, and program it to operate in two different modes, namely Access point (AP) mode, and Station (STA) mode. In AP mode, NodeMCU will work like a Wi-Fi router emitting its own Wi-Fi signal, you can use any smartphone to connect to this Wi-Fi network and open a web-page in which we can configure the new Wi-Fi SSID and Password, once the new credentials are set the NodeMCU will automatically get into Station mode and connect to this new Wi-Fi. The new Wi-Fi SSID and Password will be remembered so that the device get connected to this network every time its normally powered on again.
