Okay... yes... this is lazy "an exercise left to the reader" step.Next you will need to modify the monitor.js script to actually take an action when a message is received. You may also want to add some additional validation to the inbound message...
Finally, wire the breakout board you just constructed to the Raspberry Pi. Pin #17 serves a very convenient 3.3 volts, which is the perfect replacement for a CR2032 battery. There is a ground pin nearby on pin #20, as well as GPIO24 right between the...
Here's the code that was used in this project, and its a simple one. This code essentially demonstrates how to use the AHT10 sensor library to read temperature and humidity, display the results on an OLED screen, and handle errors. The delays between...
The next step of this project was to put everything together to create a basic PCB that would contain all of the components we used to create the breadboard version, in addition to a lithium cell with a charge discharge circuit to power the XIAO module,...
Let's have a look at the design of this TEMP Meter project, which was made in Fusion360. The first holder that we modeled is made up of an upper and a lower holder that are both going to be tightened to the handle of the motorcycle. This holder is attached...
Using two M2 screws, we first attach the basic lever component to the TEMP circuit. Two holes have already been created on the PCB for mounting the screws with the lever part.Next, we mount the lever part assembly with the upper holder using two washers...
Let us now analyze the main control circuit. Three sections make up this circuit: the XIAO M0 Microcontroller section, the MAX6675 Setup, and the AC section, which is connected to an isolated SMPS and relay. Let us begin with the primary part of this...
Here's the code used in this build: const int LED = 0; const int threshold = 150;//cuttoff temp MAX6675 thermocouple(thermoCLK, thermoCS, thermoDO); void setup() { display.begin(SSD1306_SWITCHCAPVCC, OLED_ADDR); pinMode(RelayPin, OUTPUT); pinMode(LED,...
This was the previous Hotplate project, which expanded the heating area by connecting the cloth iron's element to a copper plate. A mechanical mechanism called a thermostat was used to control the heating element of the original version of the hotplate....
We use four M5 bolts and nuts to mount the heating element. To hold the four bolts in place, we first set them in the correct spots and tightened them with an M5 nut on each of them.Next, we place a nut on each bolt.The heating element plate was then...
The wiring followed next, and it was really simple. We started by connecting the K-type thermistor terminals to the CON2 screw terminal port that was supplied on the circuit. The AC Heating Element Terminals are next connected to the CON2 screw terminal,...
As verified in the previous step, the hotplate is functioning as expected. The cutoff feature can be adjusted in the code because, after a few uses, it is evident that the temperature of the TOP surface and the temperature probe aluminum block differ;...
To update the TOTP authenticator you need the following: * A authenticator with the dfu bootloader installed (prebuild bootloader can be found here. * Dfu util * New software To install the new firmware follow the following steps: 1. Hold the "enter"...
The clock can be built in 4 or 5 meetings with kids. Recommend ages 10 - 18. Younger kids will need more help. One person can handle 8 - 10, with more you will need some help First meeting 1. I talk about what an...
