Hi everyone ! In this video, I am going to show you how to make a ‘Tally Counter’ by using a Calculator. These are the materials required to make this project. Take a calculator and remove the back cover. Locate the two traces on the circuit board
which connects with the ‘equals to’ (=) key. Solder two wires on to these two traces. Cover it back and solder a momentary switch to rest of the two wire ends. With this, our Tally Counter is ready. Thanks for watching… Do subscribe for more such videos.
