Convenient way to add plenty of environmental information with limited number of wires. Four BME280s can deliver four pressure+temperature+humidity sets with six wires (Vcc,Gnd,2x SDA&SCL), while allowing four of those to be shared with other I²C...
In accordance to the schematic, an inline 3M Ohm resistor is required for the leak detector to operate. Achieve this with 3 x 1M Ohm resistors in series. Also make sure that the leg of each reed switch that is not connected to Tiger M5 is connected to...
The 8-way HAT for the M5 Stick C Plus ‘Tiger’ requires an 8-way Micro JST male socket and an 8-way 90-degree header to be soldered together. Hot glue has been used to mechanically reinforce the solder joints at the header end. All pins have straight...
For best results try to bend them so they are a friction fit on the two remaining switch lugs, this helps with soldering. Position the diodes in such a way that the stripes on them are facing each other. The one on the side of the spring needs to lay...
Modify the both C files:- u8x8_d_sdl_128x64.c- u8x8_sdl_key.cThe include should be "SDL2/SDL.h" instead of "SDL.h"#ifndef NO_SDL #include "SDL2/SDL.h" #endif /* return ascii key value or -1 */ int u8g_sdl_get_key(void)
The 8-way HAT for the M5 Stick C Plus ‘Mako’ requires an 8-way Micro JST male socket and an 8-way 90-degree header to be soldered together. All pins have straight through connections. There is also a resistor and phototransistor that needs to be connected...
Solder the third 10pin female headers horizontally (left to right (C'0)(C'1)(C'2)(C'3)(C'4)(C'5)(C'6)(C'7)(C'8)(C'9)). Solder wires between C8-C'8 and C9-C'9. Solder a third pair of caps between C'8 and C'9. Solder a second veritical bus of pads on your...
You can modify the source file lcd6.c with one of available editors: vi, med or re. Use "make lcd6" to recompile. Full sources of the demo are available on GitHub: lcd6.c
When everything is assembled now it is time to test it, and maybe set the control values. I found that the following values fit good to my setup.MAX = 49°C.----- Is set to 49°C because measurements a little over 50°C triggers the overtemp...
TSOC_NEOLED Arduino Sketch ExamplesUnder the "examples" directory are several Arduino IDE examples for using the TSOC_NEOLED board with Arduino IDE. Using the Arduino "Wire" library for I2C communications, it is simple to control the TSOC_NEOLED // Start...
