![]() ![]() This project automates this process of turning lights on and off for the most common tasks. For instance a Standard Speech should be between 5 and 7 minutes: you get a green light when you reach the 5 minute mark, a yellow light at 6 minute and red one after 7 minutes. Toastmasters Timer is basically a timer-controlled traffic light with some presets for specific tasks which are time-bound at any Toastmasters meeting. That's when I decided to find a nice project to my Arduino Nano. This timing process often is manual, error-prone and a little boring. Take a look, you'll probably find a club near you that you can visit to learn a little more.Īnyway, one of the things we learn at Toastmasters is to deliver speeches and, on top of other evaluation criteria, we have a person controlling the time of your speech, as we have to keep it between specified thresholds. Replace this interface (LCD, buttons and LEDs) for a 7" touch screen, completely revamping the user interface.Small board - great value (Or how a little Arduino Nano is improving our Toastmasters meetings)įor those who are still wondering what Toastmasters ( ) means, this is as non-profit organization which helps people develop their communication and leadership skills.Then we would be able to control the traffic light without the need for additional wiring. Add the relay board remotely, by adding radio capabilities with the nRF24L01 boards.I know some clubs have cool/bigger traffic lights controlled by switches. Add a relay-board so we can control some bigger traffic lights with 127 V light bulbs.Replace the 16x2 LCD for a bigger one, 20x4, so we'll have space to show if we're in the grace period or not as well as other useful information.The only libraries needed are SPI and LiquidCrystal (you should have that as part of you Arduino IDE basic installation). The code is straightforward and I added comments to the major sections of it. I also added a little round frame for each set of LEDs to make it more evident.Īn idea for the future is to 3D print this, instead of using paper as I did (my 3D printer is currently offline for some improvements). ![]()
