I had little time for writing code. First is simple pick and drop and second is following my hand. It still need some work and sensor calibrating because they are not very useful.. Some short videos..
Finally the kit for robot hand has arrived.
First assembly of kit and servos..
And video of first test is working better then I expected
Another project for a friend of mine. Temperature monitor with DS18B20 sensor, arduino nano, esp8266 and lcd 4x20.
Soldering and instalation finished
Test run - all good waiting for housing..
Because the color display from previous post got used in other project in have remember that and old android Chinese tablet is still lies in the corner so i have made myself a big screen temperature monitor with simple android app...
I added lcd display and changed code so it has two modes:
- manual it can be guided with buttons
- auto where it drives alone on parameters that are stored - pointed
Here it is a test video:
Simple robohand with 3 servo motors an arduino mega. This is just the test it will be upgraded with the display and auto mode.
Because i have one arduoni mega board free it is time for a little playing :)
- board arduino mega
- driver board for dc motors
- lcd 4x20
- servo motor
- 4 infra led sensors
- ultrasnoic sensor on servo motor
A bsic soding is already finished it is time for little more detailed....
After one month the sensor for measuring temperature of water died. Apparently homemade water seal started to leak. So new sensor is in and conector to cables is added for easy repair if it is necessary.
the operation :D
The results are back, one graf is ready and waiting for outside temperature.
New lcd 4x20 is also here, it will show collected data for better view - like a weather station
I have finally had some time to finish circuit and test it. I measures temperature of room, humidity in room, temperature of water in aquarium in flow of water filter. For temperature in the room and humidity is used dht 11 sensor, for water temperature ds18b20 with arudino uno and esp for wifi. Data can be seen on Thingspeak, on link to my channel: https://thingspeak.com/channels/29193
It steel needs temperature of outside but my rf link died again, second pair.. Thats why I will use arudino nano and another esp for wifi. It is more reilabile.
