7th girls and boys working with SSD (Seven Segment Displays)

The SSD’s had really picked up during the project period with the 7th children after Barani had created a project. The girls started to understand and light up the letters they wanted. They used the multi meter in diode mode to test whether the SSD’s where common anode or common cathode in configuration. Initially they were powering up the SSD’s with a 9V battery, then they started to use the arduino.

Along with them Nirmal had also joined the team and started to understand SSD’s with the support of Shalini and Sushma.
