Hello all

tinyduino is my first experience with arduino

I am looking to connect a 3 wire load cell wired up with a half bridge and a hx711 amplifier to the tinyduino with a matrix led to display the load

I would appreciate any help when it comes to how to connect the hx711 to the tinyduino while also connecting the tinyduino matrix led as well as any recommendations/sample code for getting it up and running

Thanks in advance

General Discussion / Problem Initializing BMP280 Sensor after SD Card Insertion
« Last post by wendolw on March 01, 2019, 12:49:25 PM »
I am configuring the BMP280 pressure sensor for a science project using instructions provided at Rocket Altimeter Logger[tinycircuits.com]. The instructions are well-written, and provide a direct interface with the device. First, I tested the TinyShield USB using the "blinking" sample code. Then, I uploaded the actual code for the pressure sensor. Initially, this also was successful. However, the remaining instructions do not provide a link to a serial monitor to display data output. To address this issue, I ran the program in the Arduino Sketchbook (Arduino.cc) environment. I transferred the written code for the sensor and data logger (4 programs: TinyShield BarometricPressure, BMP280.CC, BMP280.h, Altimeter_DataLogger) to the Sketchbook to monitor its output on the Serial Monitor. The board and port designations were correct. I was able to obtain sequential output (time-temp-pressure) from the device, displayed on the serial monitor. However, when I attempted to load the SD card to download the data (turning off the device before inserting the SD card), the sensor stopped working. On the serial monitor, I received an error message, "BMP Init failed". It appears that running the code in the Arduino.cc environment is compromised when the SD card is introduced to download the data, leaving definitions of the BMP280, imprecise. Please provide general feedback, or a specific recommendation for, a) code correction for the data output interface, and/or b) how to secure a link to the serial monitor on the Rocket Altimeter Logger page. Thank you.

Littlejohn,

It's actually not a heater, It's a refrigerator. Although with a mod in the program to change the allowable set point range, it could be used for a heater. Provided that the heater only required one closure contact.

Creating a fully fledged HVAC thermostat would also be possible, After all a basic HVAC thermostat is nothing more than temp measurement and outputs controlled by code.

User Projects / Code Examples / Tinyscreen+ AMG thermal camera
« Last post by littlejohn on February 25, 2019, 01:52:09 AM »
I made a tiny thermal camera with a Tinyscreen+ and an AMG Grideye sensor from Adafruit. Three of the buttons are used: to control the colormap, the interpolation mode, and emphasis. It has a pretty good framerate. It needs a 3d printed case, but I haven't got that far. Here is a picture and some code.

Since i'm not happy with the thermostat on on my rv, I decided to build a new one. Basic Components are.
TinyScreen+
Custom Interface Board.
 Major components on the i/o board are
2 NO switches
Opto Isolator with transistor output Or smt SSR
Connectors for power, output of Opto-Isolator and connection for DS18B20 temp sensor.

Program allows for setting Temp set point. Has predefined sleep mode, OFF/ON hysterisis, Attached is a pic.

Cool. what kind of heater is it?

TinyDuino / TinyZero and MicroSD Shield
« Last post by buchankn on February 20, 2019, 08:36:34 PM »
Does the TinyZero work with the MicroSD shield? I just ordered these, and wanted to make sure they'll work together. My main concern was the 3.3 V coming from the TinyZero, which looks like it goes into another 3.3 volt regulator on the MicroSD shield. Does the regulator on the SD shield need > 3.3 volts to work?

Thanks!
