Like SDA5708: 8 character 7x5 dot matrix LED display, this display is received as gift for test.
For control this display with Arduino sketch must download KTMS1201.h file and put in same directory with sketch:
and in Arduino IDE software you see:
First step was to made a pcb for schematic with a 10..20k variable resistor for contrast:
Schematic is made after nest info:
Test schematic is:
After upload the example sketches and few changes in sketches, on display I can see:
After that, I made a new schematic with DHT22 (AM2302) sensor:
I write a sketch named KTMS1201_DHT22.ino and on display I can see:
I finished the schematic with RTC clock module (made with DS3231, but work fine with DS1307) and KY-040 rotary encoder:
After upload KTMS1201_DHT22_RTC_ver1m0.ino sketch, I cand see:
- hour:
- humidity and temperature:
- data, after a short push:
- change mode, first year, after a long push (3-4 seconds):
- change month:
- change day:
- change hours:
- change minutes:
I made few movie:
Final sketch is KTMS1201_DHT22_RTC_ver1m1.ino and I use a changed KTMS1201.h file for C and Y letters:
Finally, I change the sketch (see KTMS1201_DHT22_RTC_ver1m1b.ino) for another style for humidity:
