Hi,
We have been watching the "News" at the top of the forum promising new features for many months, but nothing has materialised. We have done the Line Following and Collision Avoidance, shall we just throw our Pi-Bots into the back of a cupboard, or is there anything else that you would like to try with them?
Recently I have been trying out Internet of Things (IoT)connections using ESP8266 WIFI units. The latest was a Pi-Bot type car that is controlled by and application running on an Android device, such as a tablet or mobile phone. It is very cheap, see www.smartarduino.com/view.php?id=94572 This car uses an ESP8266-12E which is the easiest to connect to a PC for programming. There is an even cheaper version here www.ebay.com/itm/ESP8266-Serial-Esp-01-WIFI-Wireless-Transceiver-Module-Send-Receive-LWIP-AP-STA-/221589414478 that can connect an Arduino or a compatible such as the STEM board on our PI-Bots into the IoT world. In fact as the ESP8266 boards run at 3.3Volts the STEM board could be better as it looks as though when the power switch is over in the 3V3 position the output pins are held at 3V3, so the ESP8266 will not be fried. I have only done some voltmeter test so far, so I not completely sure that this is true.
Have a look at Blynk, at www.blynk.cc/ ,one of the possible applications that could control our Pi-Bots and also display information from the Pi-Bot back to the controlling application via the ESP8266-01.
Has anyone else been looking at this area?
I have noticed that we are getting a few guests on the forum each day, so I hope some of them have Pi-Bots and are interested going even further.
Regards to All
John
