Lego-Car (WeMos Mini D1 and L293D Motor Shield)

Hi Blynkers, I’ve done a small Car with Legos and before let my daughter play with it, I just wanted to share the monster! The motor shield is the L293D adapted to the Wemos size. I can share the details if needed. [image] [image] [image] [image] You can find the code below, it has been prepared to be updated via OTA, based on the one I posted time ago for an Arduino Nano and the ESP-01 as shield (you can find the topic HERE), and improved using pieces of code obtained from @Costas (t…

Very simple robot 2w with L293D and Blynk controlled

Hi makers, this is my first project with blynk…is a robt controlled by Blynk but i don’t use the motor scheld, i use the fantastic L293D. In this project is very important to don’t use the pin used by Wifi sheld! First the L293 connection and pin numbers https://www.boxelectronica.com/pt/circuitos-integrados/293-l293d-dual-h-bridge-motor-driver-for-dc-or-steppers.html second the wiring [image] …the skech /* Inspired by http://circuitdigest.com/microcontroller-projects/arduino-wifi-con…

NodeMCU - ESP8266 Robot with Stand Alone Library

I have finally found a solution to the controlling a robot using the ESP8266 Solution without the need of an Arduino development board. I am using the NodeMCU board and a cheap two wheel drive platform and a motor driver adapter board that connects in a manor similar to an Arduino shield. I had help some good advice from various members of the Blynk Community and the Blynk staff that is often active in chat. Special thanks to members Psoro, katzworld and Lichtsignaal. Their assistance greatly re…

esp8266/NodeMCU Robot WORKING! untethered!

I have been building and testing out a few robots recently and want to share the great success. I toss together a robot chassis based off 2 motors and a little motor controller and a nodeMCU/esp8266 board and a led. once I got it to work and after the recent update the robot is running around the house controlled by my daughter who is “LOVING THIS!!!” with a nexus7 tablet I had posted on twitter before about it being tethered to the laptop via USB but now its full roaming wifi robot https://…
