Hi well basically i have a hobby in RC cars. A few week back i started to make circuits using the 555 timer but now i want to make them on board. i have cut some board and have soldered all the components on. the only change ive made to the circuit is a 100uf capacitor instead of a 10uf one. the circuit does nto seem to flash the LED. it simply just stays on and i checked everything and no legs touch and everything goes where it should any ideas? i dont know if this is in the right section but i saw somethign else about a 555 here so i posted it here! AsH~
