8951 Microcontroller Robotic car Project Blog diagram Robotic Car is a miniature ancestor car powered by batteries whose assorted movements can be ascendancy either manually or automatically, or the aggregate of both. Here the command is accustomed through keyboard; it would accept been bigger if we acclimated IR alien ascendancy or article of that affectionate [...]

This is a burglar alarm circuit written by Ron J. Its features include automatic Exit and Entry delays and a timed Bell/Siren Cut-Off. It’s designed to be used with the usual types of normally-closed input devices such as – magnetic reed contacts – micro switches – foil tape – and PIRs. But it can be [...]
Skema Rangkaian Jam Digital The figure on the right is displaying the condition to be displaying 10:32:54 p.m. switching every 500 milliseconds. In the switching time of the actual circuit, it is 1 millisecond. So, all digit sees to be displayed at the same time. The light of the LED is 1/6 compared with the [...]
The line follower robot with wireless video camera. I have designed it just for fun. First I want to know how the line sensor work. I used comparator IC using LM339, two H-bridge sensor using eight transistors, FCS9013, and four transistors, FSC 9012. For the sensor you can use LED and LDR as the light [...]
This simple counter can be used to count pulses, as the basis for a customer counter (like you see at the doors of some stores), or for anything else that may be counted. The circuit accepts any TTL compatible logic signal, and can be expanded easily (see Notes). Counter 7 Segment Schematic: 7 Segment Display [...]
